Mouse anti Human SOCS-3 antibody, clone SO1 recognizes the human suppressor of cytokine signaling 3 protein, also known as SOCS-3, cytokine-inducible SH2 protein 3 or STAT-induced STAT inhibitor 3. SOCS-3 is a 225 amino acid member of the suppressor of cytokine signaling family (Starr et al. 1997) containing a single SH2 and a single SOCS box domain. SOCS-3 acts as a negative regulator of janus kinase (JAK) and signal transducer and activators of transcription (STAT) signaling pathways.

SOCS-3 specifically acts as a negative feedback regulator for the STAT3 pathways, by directly binding to the Tyr-759 motif of the IL-6 signal-transducing receptor subunit gp130, thereby preventing the IL-6 activation of STAT3.

The expression of SOCS-3 is inducible by numerous factors, including IL-6, IL-10, toll-like receptor (TLR) agonists and interferon (IFN) gamma, making this protein the focus of research into inflammatory diseases such as arthritis, colitis and Crohn’s disease (Elliott and Johnstone 2004). SOCS-3 expression has also been shown to affect IFN alpha sensitivity in tumor studies (Brender et al. 2001).

Notch signaling plays a critical role in the determination of M1 versus M2 macrophage polarization. RBPJ–mediated notch signaling regulates this polarization through SOCS-3 (Narayana and Balaji 2008, Schroeder and Just 2000).

Mouse anti Human SOCS-3 antibody recognizes human SOCS-3 as a single band of ~25 kDa in MCF7 cell lysates by western blotting under reducing conditions. This antibody also cross reacts with SOCS-3 from murine cell lines.
