SOCS (suppressors of cytokine signaling) box of SOCS3-like proteins. Together with CIS1, the CIS/SOCS family of proteins is characterized by the presence of a C-terminal SOCS box and a central SH2 domain. SOCS3, like CIS1 and SOCS1, is involved in the down-regulation of the JAK/STAT pathway. SOCS3 inhibits JAK activity indirectly through recruitment to the cytokine receptors. SOCS3 has been shown to play an essential role in placental development and a non-essential role in embryo development. 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.
No pairwise interactions are available for this conserved domain.
Tips:  If you've navigated here from a protein, hovering over a position on the weblogo will display the corresponding protein position for that domain position. The histograms below the weblogo indicate mutations found on the domain. Red is for disease (OMIM) and blue is for SNPs. Functional Features are displayed as orange boxes under the histograms. You can choose which features are displayed in the box below. Range on the Protein: Protein ID Protein Position Domain Position:
