SOCS3

SOCS3基因的表达可由多种细胞因子的诱导，包括 IL-6，IL-10，干扰素-γ(IFN-γ)。

在 IL-6，Epo，GCSF 和瘦素的信号传导中，已发现SOCS3在各自的细胞因子受体上的结合对 SOCS3的抑制功能而言是至关重要的。

SOCS3的过表达会抑制脂肪组织和肝脏胰岛素信号转导，但对肌肉则不然。[7] 但是在小鼠骨骼肌中敲除 SOCS3可以保护小鼠免于肥胖相关的胰岛素抵抗。[7]

由于神经酰胺合成的增加，SOCS3会增加瘦素抵抗和胰岛素抵抗。[8] 因此，研究已表明去除 SOCS 基因可以预防肥胖症患者的胰岛素抵抗[7]

对该小鼠中基因的同源基因的研究表明，该基因在胎儿肝脏造血和胎盘发育的负调控中发挥作用。[9]

SOCS3蛋白能与JAK2结合，抑制其活性。

已经证明 SOCS3可以与下列物质相互作用:

• 促红细胞生成素受体[10][11]
• 糖蛋白130[12]
• 胰岛素样生长因子1受体[13]
• JAK2[6][10][14]
• PTPN11[12]
• RAS p21蛋白激活因子1[15]

有部分证据表明 SOCS3的表达受小分子核糖核酸 miR-203的调控。[16][17]
