Domain relationships


This entry represents the SOCS (suppressors of cytokine signaling) box of SSB2 (SPRY domain-containing SOCS box proteins). SSB proteins contain a central SPRY domain and a C-terminal SOCS. SSB2 has been shown to interact with c-Met, the hepatocyte growth factor receptor [PMID: 15713673, PMID: 19154741]. It also regulates inducible nitric oxide synthase (iNOS) by targeting it for proteasomal degradation [PMID: 24813479].

The general function of the SOCS box is the recruitment of the ubiquitin-transferase system. The SOCS box interacts with Elongins B and C, Cullin-5 or Cullin-2, Rbx-1, and E2. Therefore, SOCS-box-containing proteins probably function as E3 ubiquitin ligases and mediate the degradation of proteins associated through their N-terminal regions [PMID: 9869640, PMID: 16675548].
