Antigen Preparation
A synthetic peptide corresponding to C-terminus of SOCS-1 protein from human and mouse origins.
Background
"Cytokines induce a variety of biological responses by binding to specific cell surface receptors and activating cytoplasmic signal transduction pathways which are suppressed by other transcriptional factors. Proteins that mediate these signals from the cell surface to the nucleus include JAKs and STATs, while SOCS (Suppressor of cytokine signaling) proteins inhibit those signaling. The SOCS family comprises at least 8 members, SOCS1 to SOCS7 and CIS (cytokine inducible SH2 containing protein). 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 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 kinase inhibition). SOCS1 is an important negative regulator of JAK-STAT signal pathway."
