Protein Information (annotations from UniProt)

Database IDHIV0010531
UniProt IDO15524
Primary gene name(s)SOCS1
Synonym gene name(s)SSI1, TIP3
Protein nameSuppressor of cytokine signaling 1
Protein functionSOCS family proteins form part of a classical negative feedback system that regulates cytokine signal transduction. SOCS1 is involved in negative regulation of cytokines that signal through the JAK/STAT3 pathway. Through binding to JAKs, inhibits their kinase activity. In vitro, also suppresses Tec protein-tyrosine activity. Appears to be a major regulator of signaling by interleukin 6, IL6 and leukemia inhibitory factor, LIF. Regulates interferon-gamma mediated sensory neuron survival, By similarity. Probable substrate recognition component of an ECS, Elongin BC-CUL2/5-SOCS-box protein E3 ubiquitin ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of target proteins. Seems to recognize JAK2. SOCS1 appears to be a negative regulator in IGF1R signaling pathway. {ECO:0000250, ECO:0000269|PubMed:11278610, ECO:0000269|PubMed:11313480}.
Subcellular locationNucleus {ECO:0000269|PubMed:16410555}. Cytoplasmic vesicle {ECO:0000269|PubMed:16410555}. Note=Detected in perinuclear cytoplasmic vesicles upon interaction with FGFR3.
