CD74

该基因编码的蛋白与Ⅱ类主要组织相容性复合体（mhc）相关，是调节免疫应答抗原提呈的重要伴侣。它还充当细胞因子-巨噬细胞移动抑制因子（mif）的细胞表面受体，mif与编码蛋白结合后，启动生存途径和细胞增殖。该蛋白还与淀粉样前体蛋白（app）相互作用，抑制淀粉样β（abeta）的产生。已经鉴定出编码不同亚型的多个选择性剪接转录变体。[由RefSeq提供，2011年8月]
The protein encoded by this gene associates with class II major histocompatibility complex (MHC) and is an important chaperone that regulates antigen presentation for immune response. It also serves as cell surface receptor for the cytokine macrophage migration inhibitory factor (MIF) which, when bound to the encoded protein, initiates survival pathways and cell proliferation. This protein also interacts with amyloid precursor protein (APP) and suppresses the production of amyloid beta (Abeta). Multiple alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Aug 2011]
