    SUBCELLULAR LOCALIZATION     intracellular
    intracellular,nuclear envelope,matrix attachement regions
  • attached to the somatic nuclear matrix through a matrix attachment region (MAR)
  • localization regulated by cellular conditions (nuclear localization being stimulated by conditions that increased cytoplasmic protein levels)
  • basic FUNCTION
  • involved in the interleukin-6 induced receptor phosphorylation and in the negative regulation of cytokine induced JAK/ STAT pathway
  • functioning downstream of cytokine receptors
  • taking part in a negative feedback loop to alternate cytokine signaling
  • negative regulator of IFN-gamma signaling
  • adaptor protein in receptor tyrosine kinase signaling pathways, modulating innate immunity
  • negative regulator of prolactin signaling and of LPS-induced macrophage activation
  • inhibiting the IFNG inflammatory response when overexpressed in keratinocytes
  • acting as negative regulator in insulin signaling and serving as one of the missing links between insulin resistance and cytokine signaling
  • may be involved in over-production of collagen from lung fibroblasts
  • having an important role in the negative regulation of both the JAK-STAT signalling cascade and the TLR pathway during the development of inflammatory bowel diseases
  • important role for host defence against viral infections through the regulation of the sensitivity of tissue cells to IFN
  • may play an important role in sepsis
  • promotes myogenic differentiation by specifically inhibiting the JAK1/STAT1/STAT3 pathway
  • SOCS1 and SOCS3 are induced upon TCR stimulation, and would play a role in activation-induced cell death by sensitizing activated T cells toward Fas-mediated apoptosis to maintain T cell homeostasis

    protein, degradation
  • supressor of TNF cell death in fibroblasts
    signaling signal transduction

    a component
    small molecule
  • interacting with the VHL/elongin B, C /CUL2/UBE2*(VCB-CUL2 complex)
  • JAK2
  • binds to the domain in the catalytic loop essential for IRS2 recognition
  • interacting with PIM1 (modulates its stability and functions)
  • binding and inhibiting JAK1
  • SOCS1 and SOCS3 exhibit enhanced adhesion and reduced migration towards the chemokine CCL11
  • interacts with oncogenic lymphocyte-specific protein tyrosine kinase (LCK)
