KIR3DS1(杀伤细胞免疫球蛋白样受体3DS1)属于KIR基因家族,这是一组编码自然杀伤(NK)细胞表面受体的基因,主要参与免疫调节和病原体防御。KIR3DS1编码一种激活型受体,通过识别特定的MHC I类分子(如HLA-Bw4)来触发NK细胞的杀伤功能,从而清除病毒感染或恶性细胞。KIR基因家族的共性在于它们均位于19号染色体上,具有高度多态性,且通过结合MHC I类分子调控NK细胞的活性,在免疫监视和妊娠中起关键作用。KIR3DS1的突变可能导致受体功能异常,例如丧失对HLA-Bw4的结合能力,从而削弱抗病毒(如HIV、HCV)或抗肿瘤免疫应答。研究发现,KIR3DS1与某些疾病密切相关,例如其特定变异可延缓HIV进展,但可能与自身免疫疾病(如类风湿关节炎)风险增加相关。若KIR3DS1过表达,可能过度激活NK细胞,导致炎症反应或组织损伤;而表达降低则可能削弱免疫防御,增加感染或癌症易感性。此外,KIR3DS1与其他KIR家族成员(如抑制型受体KIR3DL1)存在功能互作,其表达失衡可能破坏免疫稳态。该基因的遗传多样性在个体化医疗和疾病风险评估中具有潜在应用价值。

Killer cell immunoglobulin-like receptors (KIRs) are transmembrane glycoproteins expressed by natural killer cells and subsets of T cells. The KIR genes are polymorphic and highly homologous and they are found in a cluster on chromosome 19q13.4 within the 1 Mb leukocyte receptor complex (LRC). The gene content of the KIR gene cluster varies among haplotypes, although several "framework" genes are found in all haplotypes (KIR3DL3, KIR3DP1, KIR3DL4, KIR3DL2). The KIR proteins are classified by the number of extracellular immunoglobulin domains (2D or 3D) and by whether they have a long (L) or short (S) cytoplasmic domain. KIR proteins with the long cytoplasmic domain transduce inhibitory signals upon ligand binding via an immune tyrosine-based inhibitory motif (ITIM), while KIR proteins with the short cytoplasmic domain lack the ITIM motif and instead associate with the TYRO protein tyrosine kinase binding protein to transduce activating signals. The ligands for several KIR proteins are subsets of HLA class I molecules; thus, KIR proteins are thought to play an important role in regulation of the immune response. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2013]
