CIS-1 Products

SOCS (suppressor of cytokine signaling) proteins, also called CIS (cytokine-inducible SH2-domain containing) proteins, are a family of eight adaptor molecules active in signaling pathways that regulate innate and adaptive immune responses. All SOCS contain a single SH2 domain and a SOCS box, which recruits E3 ubiquitin ligase complexes, thus enhancing destruction of the molecules bound by SOCS proteins. SOCS proteins influence macrophage and dendritic cell activation and are essential for T cell development and differentiation.
