The first LIM domain of Testin-like family; The first LIM domain of Testin_like family: This family includes testin, prickle, dyxin and LIMPETin. Structurally, testin and prickle proteins contain three LIM domains at C-terminal; LIMPETin has six LIM domains; and dyxin presents only two LIM domains. However, all members of the family contain a PET protein-protein interaction domain. Testin is a cytoskeleton associated focal adhesion protein that localizes along actin stress fibers, at cell-cell-contact areas, and at focal adhesion plaques. Testin interacts with a variety of cytoskeletal proteins, including zyxin, mena, VASP, talin, and actin and it is involved in cell motility and adhesion events. Prickles have been implicated in roles of regulating tissue polarity or planar cell polarity (PCP). Dyxin involves in lung and heart development by interaction with GATA6 and blocking GATA6 activated target genes. LIMPETin might be the recombinant product of genes coding testin and four and half LIM proteins and its function is not well understood. As in other LIM domains, this domain family is 50-60 amino acids in size and shares two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms. LIM domains function as adaptors or scaffolds to support the assembly of multimeric protein complexes.

PET ((Prickle Espinas Testin) domain is involved in protein-protein interactions; PET domain is involved in protein-protein interactions and is usually found in conjunction with LIM domain, which is also a protein-protein interaction domain. The PET containing proteins serve as adaptors or scaffolds to support the assembly of multimeric protein complexes. The PET domain has been found at the N-terminal of four known groups of proteins: prickle, testin, LIMPETin/LIM-9 and overexpressed breast tumor protein (OEBT). Prickle has been implicated in regulation of cell movement through its association with the Dishevelled (Dsh) protein in the planar cell polarity (PCP) pathway. Testin is a cytoskeleton associated focal adhesion protein that localizes along actin stress fibers, at cell contact areas, and at focal adhesion plaques. It interacts with a variety of cytoskeletal proteins, including zyxin, mena, VASP, talin, and actin, and is involved in cell motility and adhesion events. Knockout mice experiments reveal tumor repressor function of Testin. LIMPETin/LIM-9 contains an N-terminal PET domain and 6 LIM domains at the C-terminal. In Schistosoma mansoni, where LIMPETin was first identified, it is down regulated in sexually mature adult females compared to sexually immature adult females and adult males. Its differential expression indicates that it is a transcription regulator. In C. elegans, LIM-9 may play a role in regulating the assembly and maintenance of the muscle A-band by forming a protein complex with SCPL-1 and UNC-89 and other proteins. OEBT displays a PET domain with two LIM domains, and is predicted to be localized in the nucleus with a possible role in cancer differentiation.

There are four LIM domains in the C-terminal of the proteins and leucine-rich LD-motifs in the N-terminal region. Members of this family are adaptor proteins to recruit key components of signal-transduction machinery to specific sub-cellular locations. Paxillin is found at the interface between the plasma membrane and the actin cytoskeleton. Paxillin serves as a platform for the recruitment of numerous regulatory and structural proteins that together control the dynamic changes in cell adhesion, cytoskeletal reorganization and gene expression that are necessary for cell migration and survival. Leupaxin is a cytoskeleton adaptor protein, which is preferentially expressed in hematopoietic cells. It associates with focal adhesion kinases PYK2 and pp125FAK and identified to be a component of the osteoclast pososomal signaling complex. Hic-5 controls cell proliferation, migration and senescence by functioning as coactivator for steroid receptors such as androgen receptor, glucocorticoid receptor and progesterone receptor.

The first LIM domain of LIMK (LIM domain Kinase ); The first LIM domain of LIMK (LIM domain Kinase ): LIMK protein family is comprised of two members LIMK1 and LIMK2. LIMK contains two LIM domains, a PDZ domain and a kinase domain. LIMK is involved in the regulation of actin polymerization and microtubule disassembly. LIMK influences architecture of the actin cytoskeleton by regulating the activity of the cofilin family proteins cofilin1, cofilin2, and destrin. The mechanism of the activation is to phosphorylates cofilin on serine 3 and inactivates its actin-severing activity, and altering the rate of actin depolymerisation. LIMKs can function in both cytoplasm and nucleus and are expressed in all tissues. Both LIMK1 and LIMK2 can act in the nucleus to suppress Rac/Cdc42-dependent cyclin D1 expression. However, LIMK1 and LIMk2 have different cellular locations. While LIMK1 localizes mainly at focal adhesions, LIMK2 is found in cytoplasmic punctae, suggesting that they may have different cellular functions. The LIM domains of LIMK have been shown to play an important role in regulating kinase activity and likely also contribute to LIMK function by acting as sites of protein-to-protein interactions. All LIM domains are 50-60 amino acids in size and share two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms. LIM domains function as adaptors or scaffolds to support the assembly of multimeric protein complexes.

The fourth LIM domain of Paxillin; The fourth LIM domain of Paxillin: Paxillin is an adaptor protein, which recruits key components of the signal-transduction machinery to specific sub-cellular locations to respond to environmental changes rapidly. The C-terminal region of paxillin contains four LIM domains which target paxillin to focal adhesions, presumably through a direct association with the cytoplasmic tail of beta-integrin. The N-terminal of paxillin is leucine-rich LD-motifs. Paxillin is found at the interface between the plasma membrane and the actin cytoskeleton. The binding partners of paxillin are diverse and include protein tyrosine kinases, such as Src and FAK, structural proteins, such as vinculin and actopaxin, and regulators of actin organization. Paxillin recruits these proteins to their function sites to control the dynamic changes in cell adhesion, cytoskeletal reorganization and gene expression. LIM domains are 50-60 amino acids in size and share two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms.

The second LIM domain of Enigma-like family; The second LIM domain of Enigma-like family: The Enigma LIM domain family is comprised of three members: Enigma, ENH, and Cypher (mouse)/ZASP (human). These subfamily members contain a single PDZ domain at the N-terminus and three LIM domains at the C-terminus. Enigma was initially characterized in humans and is expressed in multiple tissues, such as skeletal muscle, heart, bone and brain. The third LIM domain specifically interacts with the insulin receptor and the second LIM domain interacts with the receptor tyrosine kinase Ret and the adaptor protein APS. Thus Enigma is implicated in signal transduction processes, such as mitogenic activity, insulin related actin organization, and glucose metabolism. The second member, ENH protein, was first identified in rat brain. It has been shown that ENH interacts with protein kinase D1 (PKD1) via its LIM domains and forms a complex with PKD1 and the alpha1C subunit of cardiac L-type voltage-gated calcium channel in rat neonatal cardiomyocytes. The N-terminal PDZ domain interacts with alpha-actinin at the Z-line. ZASP/Cypher is required for maintenance of Z-line structure during muscle contraction, but not required for Z-line assembly. In heart, Cypher/ZASP plays a structural role through its interaction with cytoskeletal Z-line proteins. In addition, there is increasing evidence that Cypher/ZASP also performs signaling functions. Studies reveal that Cypher/ZASP interacts with and directs PKC to the Z-line, where PKC phosphorylates downstream signaling targets.

The fourth LIM domain of Leupaxin; The fourth LIM domain of Leupaxin: Leupaxin is a cytoskeleton adaptor protein, which is preferentially expressed in hematopoietic cells. Leupaxin belongs to the paxillin focal adhesion protein family. Same as other members of the family, it has four leucine-rich LD-motifs in the N-terminus and four LIM domains in the C-terminus. It may function in cell type-specific signaling by associating with interaction partners PYK2, FAK, PEP and p95PKL. When expressed in human leukocytic cells, leupaxin significantly suppressed integrin-mediated cell adhesion to fibronectin and the tyrosine phosphorylation of paxillin. These findings indicate that leupaxin may negatively regulate the functions of paxillin during integrin signaling. LIM domains are 50-60 amino acids in size and share two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms.

The first LIM domain of LIMK2 (LIM domain Kinase 2); The first LIM domain of LIMK2 (LIM domain Kinase 2): LIMK2 is a member of the LIMK protein family, which comprises LIMK1 and LIMK2. LIMK contains two LIM domains, a PDZ domain, and a kinase domain. LIMK is involved in the regulation of actin polymerization and microtubule disassembly. LIMK influences architecture of the actin cytoskeleton by regulating the activity of the cofilin family proteins cofilin1, cofilin2, and destrin. The mechanism of the activation is to phosphorylates cofilin on serine 3 and inactivates its actin-severing activity, altering the rate of actin depolymerization. LIMK activity is activated by phosphorylation of a threonine residue within the activation loop of the kinase by p21-activated kinases 1 and 4 and by Rho kinase. LIMKs can function in both cytoplasm and nucleus. Both LIMK1 and LIMK2 can act in the nucleus to suppress Rac/Cdc42-dependent cyclin D1 expression. LIMK2 is expressed in all tissues. While LIMK1 localizes mainly at focal adhesions, LIMK2 is found in cytoplasmic punctae, suggesting that they may have different cellular functions. The activity of LIM kinase 2 to regulate cofilin phosphorylation is inhibited by the direct binding of Par-3. LIMK2 activation promotes cell cycle progression. The phenotype of Limk2 knockout mice shows a defect in spermatogenesis. The LIM domains have been shown to play an important role in regulating kinase activity and likely also contribute to LIMK function by acting as sites of protein-to-protein interactions. All LIM domains are 50-60 amino acids in size and share two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms. LIM domains function as adaptors or scaffolds to support the assembly of multimeric protein complexes.

The LIM domain of LIM and SH3 Protein (LASP); The LIM domain of LIM and SH3 Protein (LASP): LASP family contains two highly homologous members, LASP-1 and LASP-2. LASP contains a LIM motif at its amino terminus, a src homology 3 (SH3) domains at its C-terminal part, and a nebulin-like region in the middle. LASP-1 and -2 are highly conserved in their LIM, nebulin-like, and SH3 domains ,but differ significantly at their linker regions. Both proteins are ubiquitously expressed and involved in cytoskeletal architecture, especially in the organization of focal adhesions. LASP-1 and LASP-2, are important during early embryo- and fetogenesis and are highly expressed in the central nervous system of the adult. However, only LASP-1 seems to participate significantly in neuronal differentiation and plays an important functional role in migration and proliferation of certain cancer cells while the role of LASP-2 is more structural. The expression of LASP-1 in breast tumors is increased significantly. As in other LIM domains, this domain family is 50-60 amino acids in size and shares two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms.

TLP is the distant member of the CRP family of proteins. TLP has two isomers (TLP-A and TLP-B) and sharing approximately 30% with each of the three other CRPs. Like CRP1, CRP2 and CRP3/MLP, TLP has two LIM domains, connected by a flexible linker region. Unlike the CRPs, TLP lacks the nuclear targeting signal (K/R-K/R-Y-G-P-K) and is localized solely in the cytoplasm. TLP is specifically expressed in the thymus in a subset of cortical epithelial cells. TLP has a role in development of normal thymus and in controlling the development and differentiation of thymic epithelial cells. CRIP is a short LIM protein with only one LIM domain. CRIP gene is developmentally regulated and can be induced by glucocorticoid hormones during the first three postnatal weeks. The domain shows close sequence homology to LIM domain of thymus LIM protein. However, unlike the TLP proteins which have two LIM domains, the members of this family have only one LIM domain. LIM domains are 50-60 amino acids in size and share two characteristic zinc finger motifs. The two zinc fingers contain eight conserved residues, mostly cysteines and histidines, which coordinately bond to two zinc atoms. LIM domains function as adaptors or scaffolds to support the assembly of multimeric protein complexes.
