| Full Name | suppressor of cytokine signaling 1 |
| Background | Accumulating evidence has demonstrated that cytokine receptor signaling is negatively regulated by a family of Src homology 2 domain-containing adaptor molecules termed SOCS (Suppressor of Cytokine Signaling). To date, there are eight members of SOCS family that have been identified; they are SOCS 1, 2, 3, 4, 5, 6, 7 and CIS. Structurally, the SOCS proteins are composed of an N-terminal region of variable length and amino acid composition, a central SH2 domain, and a previously unrecognized C-terminal motif named the SOCS box. SOCS proteins appear to form part of a classical negative feedback loop that regulates cytokine signal transduction via a STAT-induced transcriptional mechanism. Transcription of each of the SOCS genes occurs rapidly in vitro and in vivo in response to cytokines. Once produced, the various members of the SOCS family appear to inhibit signaling in different ways. SOCS 1 inhibition of signal transduction appears to occur by binding to and inhibiting the catalytic activity of members of JAK family of cytoplasmic kinases (direct JAK2 kinas inhibition). Biochemical characterization as well as gene disruption studies indicate that SOCS 1 is an important negative regulator of JAK-STAT signal pathway. SOCS 1 is also called JAB SSI 1 or TIP3 (Tec-Interacting Protein). |
