SOCS7 is a member of the suppressor of cytokine signaling family of proteins. SOCS7 functions in insulin signaling and glucose homeostasis through IRS1 ubiquitination and subsequent proteasomal degradation []. SOCS7 inhibits also prolactin, growth hormone and leptin signaling by preventing STAT3 and STAT5 activation, sequestering them in the cytoplasm and reducing their binding to DNA [].

This entry represents the SOCS box domain of SOCS7.SOCS7 is a member of the suppressor of cytokine signaling family of proteins. SOCS7 functions in insulin signaling and glucose homeostasis through IRS1 ubiquitination and subsequent proteasomal degradation []. SOCS7 inhibits also prolactin, growth hormone and leptin signaling by preventing STAT3 and STAT5 activation, sequestering them in the cytoplasm and reducing their binding to DNA [].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 [, ].
