这个基因编码的蛋白质是一种主要由单核细胞产生的细胞因子，在一定程度上由淋巴细胞产生。这种细胞因子在免疫调节和炎症中有多种作用。下调巨噬细胞th1细胞因子、mhcⅡ类ags和共刺激分子的表达。它还可以增强b细胞的存活、增殖和抗体的产生。该细胞因子可阻断NF-卡帕B活性，参与JAK-STAT信号通路的调节。小鼠的基因敲除研究表明，这种细胞因子在肠道中起着重要的免疫调节作用。该基因的突变与hiv-1感染和类风湿关节炎的易感性增加有关。
The protein encoded by this gene is a cytokine produced primarily by monocytes and to a lesser extent by lymphocytes. This cytokine has pleiotropic effects in immunoregulation and inflammation. It down-regulates the expression of Th1 cytokines, MHC class II Ags, and costimulatory molecules on macrophages. It also enhances B cell survival, proliferation, and antibody production. This cytokine can block NF-kappa B activity, and is involved in the regulation of the JAK-STAT signaling pathway. Knockout studies in mice suggested the function of this cytokine as an essential immunoregulator in the intestinal tract. Mutations in this gene are associated with an increased susceptibility to HIV-1 infection and rheumatoid arthritis.[provided by RefSeq, May 2011]
