这个基因编码免疫球蛋白超家族的一个成员编码的蛋白质包含一个免疫球蛋白（Ig）结构域，是一个受体，通过传递抑制信号来抑制免疫应答选择性剪接导致多个转录变体这个基因的多态性与类风湿关节炎的风险增加有关[由RefSeq提供，2011年8月]
This gene encodes a member of the immunoglobulin superfamily. The encoded protein contains a single immunoglobulin (Ig) domain and is a receptor that relays inhibitory signals to suppress the immune response. Alternative splicing results in multiple transcript variants. Polymorphisms in this gene have been associated with an increased risk of rheumatoid arthritis. [provided by RefSeq, Aug 2011]
