词条 | TRAF4 |
释义 |
TRAF4 is a member of the TNF receptor associated factor (TRAF) family, a family of scaffold proteins.[4] TRAF proteins connect IL-1R/Toll and TNF receptors with signaling factors that lead to the activation of NF-κB and mitogen-activated protein kinases. However, TRAF4 is not known to interact with TNF receptors and its cellular functions are not well understood.[5] Protein interactionsTRAF4 has been shown to interact with neurotrophin receptor, p75 (NTR/NTSR1),[6][7] and negatively regulate NTR induced cell death and NF-kappa B activation. This protein has been found to bind to p47phox, a cytosolic regulatory factor included in a multi-protein complex known as NAD(P)H oxidase. This protein thus, is thought to be involved in the oxidative activation of MAPK8/JNK. Alternatively spliced transcript variants have been observed but the full-length nature of only one has been determined.[3] A recent report indicates that TRAF4 binds to NOD-Like Receptors NOD1 and NOD2, and specifically inhibits activation of NF-κB by the activated NOD2-RIP2 complex [8] References1. ^{{cite journal | vauthors = Regnier CH, Tomasetto C, Moog-Lutz C, Chenard MP, Wendling C, Basset P, Rio MC | title = Presence of a new conserved domain in CART1, a novel member of the tumor necrosis factor receptor-associated protein family, which is expressed in breast carcinoma | journal = J Biol Chem | volume = 270 | issue = 43 | pages = 25715–21 |date=Dec 1995 | pmid = 7592751 | pmc = | doi =10.1074/jbc.270.43.25715 }} {{Clear}}2. ^{{cite journal | vauthors = Tomasetto C, Regnier C, Moog-Lutz C, Mattei MG, Chenard MP, Lidereau R, Basset P, Rio MC | title = Identification of four novel human genes amplified and overexpressed in breast carcinoma and localized to the q11-q21.3 region of chromosome 17 | journal = Genomics | volume = 28 | issue = 3 | pages = 367–76 |date=Jan 1996 | pmid = 7490069 | pmc = | doi = 10.1006/geno.1995.1163 }} 3. ^1 {{cite web | title = Entrez Gene: TRAF4 TNF receptor-associated factor 4| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=9618| accessdate = }} 4. ^{{cite journal | vauthors = Wajant H, Henkler F, Scheurich P | title = The TNF-receptor-associated factor family: scaffold molecules for cytokine receptors, kinases and their regulators | journal = Cell.
