23-71 | 4.48e-06 | ||
SAM domain of Polycomb group; SAM (sterile alpha motif) domain of Polycomb group is a protein-protein interaction domain. The Polycomb group includes transcriptional repressors which are involved in the regulation of some key regulatory genes during development in many organisms. They are best known for silencing Hox (Homeobox) genes. Polycomb proteins work together in large multimeric and chromatin-associated complexes. They organize chromatin of the target genes and maintain repressed states during many cell divisions. Polycomb proteins are classified based on their common function, but not on conserved domains and/or motifs; however many Polycomb proteins (members of PRC1 class complex) contain SAM domains which are more similar to each other inside of the Polycomb group than to SAM domains outside of it. Most information about structure and function of Polycomb SAM domains comes from studies of Ph (Polyhomeotic) and Scm (Sex comb on midleg) proteins. Polycomb SAM domains usually can be found at the C-terminus of the proteins. Some members of this group contain, in addition to the SAM domain, MTB repeats, Zn finger, and/or DUF3588 domains. Polycomb SAM domains can form homo- and/or heterooligomers through ML and EH surfaces. SAM/SAM oligomers apparently play a role in transcriptional repression through polymerization along the chromosome. Polycomb proteins are known to be highly expressed in some cells years before their cancer pathology; thus they are attractive markers for early cancer therapy.

SAM domain of SAM_Neurabin-like subfamily; SAM (sterile alpha motif) domain of Neurabin-like (Neural actin-binding) subfamily is a putative protein-protein interaction domain. This group currently includes the SAM domains of neurobin-I, SAMD14 and neurobin-I/SAMD14-like proteins. Most are multidomain proteins and in addition to SAM domain they contain other protein-binding domains such as PDZ and actin-binding domains. Members of this subfamily participate in signal transduction. Neurabin-I is involved in the regulation of Ca signaling intensity in alpha-adrenergic receptors; it forms a functional pair of opposing regulators with neurabin-II. Neurabins are expressed almost exclusively in neuronal cells. They are known to interact with protein phosphatase 1 and inhibit its activity; they also can bind actin filaments; however, the exact role of the SAM domain is unclear, since SAM doesn't participate in these interactions.

23-85 | 1.06e-05 | ||
SAM domain of Scm proteins of Polycomb group; SAM (sterile alpha motif) domain of Scm (Sex comb on midleg) subfamily of Polycomb group is a protein-protein interaction domain. Proteins of this subfamily are transcriptional repressors associated with PRC1 complex. This group includes invertebrate Scm protein and chordate Scm homolog 1 and Scm-like 1, 2, 3 proteins. Most have a SAM domain, two MBT repeats, and a DUF3588 domain, except Scm-like 4 proteins which do not have MBT repeats. Originally the Scm protein was described in Drosophila as a regulator required for proper spatial expression of homeotic genes. It plays a major role during early embryogenesis. SAM domains of Scm proteins can interact with each other, forming homooligomers, as well as with SAM domains of other proteins, in particular with SAM domains of Ph (polyhomeotic) proteins, forming heterooligomers. Homooligomers are similar to the ones formed by SAM Pointed domains of the TEL proteins. Such SAM/SAM oligomers apparently play a role in transcriptional repression through polymerization along the chromosome. Mammalian Scmh1 protein is known be indispensible member of PRC1 complex; it plays a regulatory role for the complex during meiotic prophase of male sperm cells, and is particularly involved in regulation of chromatin modification at the XY chromatin domain of the pachytene spermatocytes.

SAM domain of CNK1,2,3-suppressor subfamily; SAM (sterile alpha motif) domain of CNK (connector enhancer of kinase suppressor of ras (Ksr)) subfamily is a protein-protein interaction domain. CNK proteins are multidomain scaffold proteins containing a few protein-protein interaction domains and are required for connecting Rho and Ras signaling pathways. In Drosophila, the SAM domain of CNK is known to interact with the SAM domain of the aveugle protein, forming a heterodimer. Mutation of the SAM domain in human CNK1 abolishes the ability to cooperate with the Ras effector, supporting the idea that this interaction is necessary for proper Ras signal transduction.

Proteins of this subfamily are multidomain diacylglycerol kinases. The SAM domain is located at the C-terminus of two out of three isoforms of DGK-eta protein. DGK-eta proteins participate in signal transduction. They regulate the level of second messengers such as diacylglycerol and phosphatidic acid. The SAM domain of DCK-eta proteins can form high molecular weight homooligomers through head-to-tail interactions as well as heterooligomers with the SAM domain of DGK-delta proteins. The oligomerization plays a role in the regulation of the DGK-delta intracellular localization: it is responsible for sustained endosomal localization of the protein and resulted in negative regulation of DCK-eta catalytic activity.

SAM domain of Atherin/Atherin-like subfamily; SAM (sterile alpha motif) domain of SAM_Atherin and Atherin-like subfamily proteins is a putative protein-protein and/or protein-lipid interaction domain. In addition to the C-terminal SAM domain, the majority of proteins belonging to this group also have PHD (or Zn finger) domain. As potential members of the polycomb group, these proteins may be involved in regulation of some key regulatory genes during development. Atherin can be recruited by Ruk/CIN85 kinase-binding proteins via its SH3 domains thus participating in the signal transferring kinase cascades. Also, atherin was found associated with low density lipids (LDL) in atherosclerotic lesions in human. It was suggested that atherin plays an essential role in atherogenesis via immobilization of LDL in the arterial wall. SAM domains of atherins are predicted to form polymers. Inhibition of polymer formation could be a potential antiatherosclerotic therapy. Pssm-ID: 188982 Cd Length: 69 Bit Score: 37.64 E-value: 4.67e-04

SAM domain of diacylglycerol kinase delta; SAM (sterile alpha motif) domain of DGK-delta subfamily proteins is a protein-protein interaction domain. Proteins of this subfamily are multidomain diacylglycerol kinases with a SAM domain located at the C-terminus. DGK-delta proteins participate in signal transduction. They regulate the level of second messengers such as diacylglycerol and phosphatidic acid. In particular DGK-delta is involved in the regulation of clathrin-dependent endocytosis. The SAM domain of DGK-delta proteins can form high molecular weight homooligomers through head-to-tail interactions as well as heterooligomers with the SAM domain of DGK-eta proteins. The oligomerization plays a role in the regulation of the DGK-delta intracellular localization: it inhibits the translocation of the protein to the plasma membrane from the cytoplasm. The SAM domain also can bind Zn at multiple (not conserved) sites driving the formation of highly ordered large sheets of polymers, thus suggesting that Zn may play important role in the function of DCK-delta.
