The Suppressor of Cytokine Signaling (SOCS) family of proteins acts in a classic negative feedback loop to regulate cytokine signal transduction. SOCS-1, also designated Janus kinase [JAK] binding protein (JAB), or STAT-induced STAT inhibitor (SSI-1), is a 24kD protein containing an SH2 domain. SOCS-1 inhibits both IL-6-induced receptor phosphorylation and STAT activation. SOCS-1 is also 45 induced by and inhibits the signaling action of IL-3, IL-4, 1 2 3 4kD 97 66 LLIF, prolactin, and erythropoietin. Additionally, SOCS-1 can associate with all 4 JAK family kinases, and is an important regulator of the JAK-STAT signaling pathway. SOCS-1 is found primarily in thymocytes, where it plays a key role in the negative regulation of IFN-g signaling and T cell differentiation.
