Death domain of the Nuclear Factor-KappaB2 precursor protein p100; Death Domain (DD) of the Nuclear Factor-KappaB2 (NF-kB2) precursor protein p100. The NF-kB family of transcription factors play a central role in cardiovascular growth, stress response, and inflammation by controlling the expression of a network of different genes. There are five NF-kB proteins, all containing an N-terminal REL Homology Domain (RHD). NF-kB2 (or p52) is produced from the processing of the precursor protein p100, which contains ANK repeats and a C-terminal DD in addition to the RHD. It is regulated by the non-canonical NF-kB pathway. The p100 precursor is cytosolic and interacts with RelB. Upon phosphorylation by IKKalpha, p100 is processed to its 52kDa active, DNA-binding form and the p52/RelB complex is translocated into the nucleus. The non-canonical pathway plays a role in adaptive immunity and lymphorganogenesis. In general, DDs are protein-protein interaction domains found in a variety of domain architectures. Their common feature is that they form homodimers by self-association or heterodimers by associating with other members of the DD superfamily including CARD (Caspase activation and recruitment domain), DED (Death Effector Domain), and PYRIN. They serve as adaptors in signaling pathways and can recruit other proteins into signaling complexes.

Transient Receptor Potential channel, Vanilloid subfamily (TRPV), types 5 and 6; TRPV5 and TRPV6 (TRPV5/6) are two homologous members within the vanilloid subfamily of the transient receptor potential (TRP) family. TRPV5 and TRPV6 show only 30-40% homology with other members of the TRP family and have unique properties that differentiates them from other TRP channels. They mediate calcium uptake in epithelia and their expression is dramatically increased in numerous types of cancer. The structure of TRPV5/6 shows the typical topology features of all TRP family members, such as six transmembrane regions, a short hydrophobic stretch between transmembrane segments 5 and 6, which is predicted to form the Ca2+ pore, and large intracellular N- and C-terminal domains. The N-terminal domain of TRPV5/6 contains three ankyrin repeats. This structural element is present in several proteins and plays a role in protein-protein interactions. The N- and C-terminal tails of TRPV5/6 each contain an internal PDZ motif which can function as part of a molecular scaffold via interaction with PDZ-domain containing proteins. A major difference between the properties of TRPV5 and TRPV6 is in their tissue distribution: TRPV5 is predominantly expressed in the distal convoluted tubules (DCT) and connecting tubules (CNT) of the kidney, with limited expression in extrarenal tissues. In contrast, TRPV6 has a broader expression pattern such as expression in the intestine, kidney, placenta, epididymis, exocrine tissues, and a few other tissues.

N-terminal sub-domain of the Rel homology domain (RHD) of nuclear factor of kappa B1 (NF-kappa B1); Proteins containing the Rel homology domain (RHD) are metazoan transcription factors. The RHD is composed of two structural sub-domains; this model characterizes the N-terminal RHD sub-domain of the NF-kappa B1 family of transcription factors, a class I member of the NF-kappa B family. In class I NF-kappa Bs, the RHD domain co-occurs with C-terminal ankyrin repeats. NF-kappa B1 is commonly referred to as p105 or p50 (proteolytically processed form). NF-kappa B proteins are part of a protein complex that acts as a transcription factor, which is responsible for regulating a host of cellular responses to a variety of stimuli. This complex tightly regulates the expression of a large number of genes, and is involved in processes such as adaptive and innate immunity, stress response, inflammation, cell adhesion, proliferation and apoptosis. The cytosolic NF-kappa B complex is activated via phosphorylation of the ankyrin-repeat containing inhibitory protein I-kappa B, which dissociates from the complex and exposes the nuclear localization signal of the heterodimer (NF-kappa B and REL). NF-kappa B1 is involved in the canonical NF-kappa B signaling pathway which is activated by many agonists and is essential in immune and inflammatory responses, as well as cell survival. p105 is involved in its own specific NF-kappa B signaling pathway which is also implicated in immune and inflammatory responses. p105 may also act as an I-kappa B due to its C-terminal ankyrin repeats. It is also involved in mitogen-activated protein kinase (MAPK) signaling as its degradation leads to the activation of TPL-2, a MAPK kinase kinase which activates ERK pathways.

IPT domain of eukaryotic transcription factors NF-kappaB/Rel, nuclear factor of activated Tcells (NFAT), and recombination signal J-kappa binding protein (RBP-Jkappa). The IPT domains in these proteins are involved in DNA binding. Most NF-kappaB/Rel proteins form homo- and heterodimers, while NFAT proteins are largely monomeric (with TonEBP being an exception). While the majority of sequence-specific DNA binding elements are found in the N-terminal domain, several are found in the IPT domain in loops adjacent to, and including, the linker region.

N-terminal sub-domain of the Rel homology domain (RHD) of the arthropod protein Relish; Proteins containing the Rel homology domain (RHD) are metazoan transcription factors. The RHD is composed of two structural sub-domains; this model characterizes the N-terminal RHD sub-domain of the arthropod Relish protein, in which the RHD domain co-occurs with C-terminal ankyrin repeats. Family members are sometimes referred to as p110 or p68 (proteolytically processed form). Relish is an NF-kappa B-like transcription factor, which plays a role in mediating innate immunity in Drosophila. It is activated via the Imd (immune deficiency) pathway, which triggers phosphorylation of Relish. IKK-dependent proteolytic cleavage of Relish (which involves Dredd) results in a smaller active form (without the C-terminal ankyrin repeats), which is transported into the nucleus and functions as a transactivator.

Death domain of the Nuclear Factor-KappaB2 precursor protein p100; Death Domain (DD) of the Nuclear Factor-KappaB2 (NF-kB2) precursor protein p100. The NF-kB family of transcription factors play a central role in cardiovascular growth, stress response, and inflammation by controlling the expression of a network of different genes. There are five NF-kB proteins, all containing an N-terminal REL Homology Domain (RHD). NF-kB2 (or p52) is produced from the processing of the precursor protein p100, which contains ANK repeats and a C-terminal DD in addition to the RHD. It is regulated by the non-canonical NF-kB pathway. The p100 precursor is cytosolic and interacts with RelB. Upon phosphorylation by IKKalpha, p100 is processed to its 52kDa active, DNA-binding form and the p52/RelB complex is translocated into the nucleus. The non-canonical pathway plays a role in adaptive immunity and lymphorganogenesis. In general, DDs are protein-protein interaction domains found in a variety of domain architectures. Their common feature is that they form homodimers by self-association or heterodimers by associating with other members of the DD superfamily including CARD (Caspase activation and recruitment domain), DED (Death Effector Domain), and PYRIN. They serve as adaptors in signaling pathways and can recruit other proteins into signaling complexes.

Immunoglobulin-like fold, Plexins, Transcription factors (IPT). IPTs are also known as Transcription factor ImmunoGlobin (TIG) domains. They are present in intracellular transcription factors, cell surface receptors (such as plexins and scatter factor receptors), as well as, cyclodextrin glycosyltransferase and similar enzymes. Although they are involved in DNA binding in transcription factors, their function in other proteins is unknown. In these transcription factors, IPTs form homo- or heterodimers with the exception of the nuclear factor of activated Tcells (NFAT) transcription factors which are mainly monomers.

Death domain of the Nuclear Factor-KappaB1 precursor protein p105; Death Domain (DD) of the Nuclear Factor-KappaB1 (NF-kB1) precursor protein p105. The NF-kB family of transcription factors play a central role in cardiovascular growth, stress response, and inflammation by controlling the expression of a network of different genes. There are five NF-kB proteins, all containing an N-terminal REL Homology Domain (RHD). NF-kB1 (or p50) is produced from the processing of the precursor protein p105, which contains ANK repeats and a C-terminal DD in addition to the RHD. It is regulated by the classical (or canonical) NF-kB pathway. In the cytosol, p50 forms an inactive complex with RelA (or p65) and the Inhibitor of NF-kB (IkB). Activation is triggered by the phosphorylation and degradation of IkB, resulting in the active DNA-binding p50-RelA dimer to migrate to the nucleus. The classical pathway regulates the majority of genes activated by NF-kB including those encoding cytokines, chemokines, leukocyte adhesion molecules, and anti-apoptotic factors. In general, DDs are protein-protein interaction domains found in a variety of domain architectures. Their common feature is that they form homodimers by self-association or heterodimers by associating with other members of the DD superfamily including CARD (Caspase activation and recruitment domain), DED (Death Effector Domain), and PYRIN. They serve as adaptors in signaling pathways and can recruit other proteins into signaling complexes.
