TNFAIP3
Tumor necrosis factor, alpha-induced protein 3 or A20 is a protein that in humans is encoded by the ''TNFAIP3'' gene. This gene was identified as a gene whose expression is rapidly induced by the tumor necrosis factor (TNF). The protein encoded by this gene is a zinc finger protein and a deubiquitinating enzyme, and has been shown to inhibit NF-kappa B activation as well as TNF-mediated apoptosis. The A20 protein is ancient, and protein homolog can be found as far back as cnidaria (corals, jellyfish, anemones) with a conserved protein domain composition. Using knockout mouse models of TNFAIP3 and its transcriptional repressor (i.e. KCHIP3), TNFAIP3 has been shown to be critical for limiting inflammation by terminating endotoxin- and TNF-induced NF-kappa B responses. In brief, deubiquitinase function of TNFAIP3 was shown to remove ubiquitin chains from VE-cadherin to prevent loss of VE-cadherin at the endothelial adherens junctions. Interactions TNFAIP3 has been shown to intera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

TRAF1
TNF receptor-associated factor 1 is a protein that in humans is encoded by the ''TRAF1'' gene. Function The protein encoded by this gene is a member of the TNF receptor (TNFR) associated factor (TRAF) protein family. TRAF proteins associate with, and mediate the signal transduction from various receptors of the TNFR superfamily. This protein and TRAF2 form a heterodimeric complex, which is required for TNF-alpha-mediated activation of MAPK8/JNK and NF-kappaB. The protein complex formed by this protein and TRAF2 also interacts with IAP, and thus mediates the anti-apoptotic signals from TNF receptors. The expression of this protein can be induced by Epstein-Barr virus (EBV). EBV infection membrane protein 1 (LMP1) is found to interact with this and other TRAF proteins; this interaction is thought to link LMP1-mediated B lymphocyte transformation to the signal transduction from TNFR family receptors. TRAF1 also functions as a negative regulator of inflammation by interfering with t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

TRAF6
TRAF6 is a TRAF human protein. Function The protein encoded by this gene is a member of the TNF receptor associated factor (TRAF) protein family. TRAF proteins are associated with, and mediate signal transduction from members of the TNF receptor superfamily. This protein mediates the signaling not only from the members of the TNF receptor superfamily, but also from the members of the Toll/IL-1 family. Signals from receptors such as CD40, TNFSF11/TRANCE/RANKL and IL-1 have been shown to be mediated by this protein. This protein also interacts with various protein kinases including IRAK1/IRAK, SRC and PKCzeta, which provides a link between distinct signaling pathways.

YWHAZ
14-3-3 protein zeta/delta (14-3-3ζ) is a protein that in humans is encoded by the ''YWHAZ'' gene on chromosome 8. The protein encoded by this gene is a member of the 14-3-3 protein family and a central hub protein for many signal transduction pathways. 14-3-3ζ is a major regulator of apoptotic pathways critical to cell survival and plays a key role in a number of cancers and neurodegenerative diseases. Structure 14-3-3 proteins generally form ~30 kDa-long homo- or heterodimers. Each of the monomers are composed of 9 antiparallel alpha helices. Four alpha-helices (αC, αE, αG, and αI) form an amphipathic groove that serves as the ligand binding site, which can recognize three types of consensus binding motifs: RXX(pS/pT)XP, RXXX(pS/pT)XP, and (pS/pT)X1-2-COOH (where pS/pT represents phosphorylated serine/threonine). In addition to these primary interactions, the target protein can also bind outside the groove via secondary interactions. In particular, the crystallized stru ...

IKBKG
NF-kappa-B essential modulator (NEMO) also known as inhibitor of nuclear factor kappa-B kinase subunit gamma (IKK-γ) is a protein that in humans is encoded by the ''IKBKG'' gene. NEMO is a subunit of the IκB kinase complex that activates NF-κB. The human gene for IKBKG is located on chromosome Xq28. Multiple transcript variants encoding different isoforms have been found for this gene. Function NEMO (IKK-γ) is the regulatory subunit of the inhibitor of IκB kinase (IKK) complex, which activates NF-κB resulting in activation of genes involved in inflammation, immunity, cell survival, and other pathways. Clinical significance Mutations in the IKBKG gene results in incontinentia pigmenti, hypohidrotic ectodermal dysplasia, and several other types of immunodeficiencies. Incontinentia Pigmenti (IP) is an X-linked dominant disease caused by a mutation in the IKBKG gene.

KCHIP3
Calsenilin is a protein that in humans is encoded by the ''KCNIP3'' gene. Function This gene encodes a member of the family of voltage-gated potassium (Kv) channel-interacting proteins, which belong to the neuronal calcium sensor family of proteins. Members of this family are small calcium binding proteins containing EF-hand-like domains. They are integral subunit components of native Kv4 channel complexes that may regulate A-type currents, and hence neuronal excitability, in response to changes in intracellular calcium. The encoded protein also functions as a calcium-regulated transcriptional repressor, and interacts with presenilins. In addition, the protein has been shown to transcriptionally repress A20 (TNFAIP3) expression and thus modulate the anti-inflammatory signaling. Alternatively spliced transcript variants encoding different isoforms have been described. Interactions Calsenilin has been shown to interact with PSEN1 and PSEN2.

VE-cadherin
Cadherin 5, type 2 or VE-cadherin (vascular endothelial cadherin) also known as CD144 ( Cluster of Differentiation 144), is a type of cadherin. It is encoded by the human gene ''CDH5''. Function VE-cadherin is a classical cadherin from the cadherin superfamily and the gene is located in a six-cadherin cluster in a region on the long arm of chromosome 16 that is involved in loss of heterozygosity events in breast and prostate cancer. The encoded protein is a calcium-dependent cell–cell adhesion glycoprotein composed of five extracellular cadherin repeats, a transmembrane region and a highly conserved cytoplasmic tail. Functioning as a classic cadherin by imparting to cells the ability to adhere in a homophilic manner, the protein may play an important role in endothelial cell biology through control of the cohesion and organization of the intercellular junctions. Integrity of intercellular junctions is a major determinant of permeability of the endothelium, and the VE-cadheri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TRAF2
TNF receptor-associated factor 2 is a protein that in humans is encoded by the ''TRAF2'' gene. Function The protein encoded by this gene is a member of the TNF receptor associated factor (TRAF) protein family. TRAF proteins associate with, and mediate the signal transduction from members of the TNF receptor superfamily. This protein directly interacts with TNF receptors, and forms complexes with other TRAF proteins. TRAF2 is required for TNF-alpha-mediated activation of MAPK8/JNK and NF-κB. The protein complex formed by TRAF2 and TRAF1 interacts with the IAP family members cIAP1 and cIAP2, and functions as a mediator of the anti-apoptotic signals from TNF receptors. The interaction of this protein with TRADD, a TNF receptor associated apoptotic signal transducer, ensures the recruitment of IAPs for the direct inhibition of caspase activation. cIAP1 can ubiquitinate and induce the degradation of this protein, and thus potentiate TNF-induced apoptosis.

Protein
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells and organisms, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific 3D structure that determines its activity. A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called peptides. The individual amino acid residues are bonded together by peptide bonds and adjacent amino acid residues. The sequence of amino acid residue ...
