基因染色体位置图

PPIA(Peptidylprolyl Isomerase A)是一种广泛存在于各种组织和细胞中的基因,编码亲环素A(Cyclophilin A),属于亲环素蛋白家族。该基因家族的主要共性是含有保守的PPIase(肽酰脯氨酰顺反异构酶)结构域,能够催化蛋白质中脯氨酸残基的顺反异构化,从而参与蛋白质折叠、稳定性和功能调节。PPIA在细胞内具有多种生物学功能,包括作为免疫抑制剂环孢素A(CsA)的主要结合靶点,参与免疫调节。此外,PPIA在细胞信号转导、炎症反应、氧化应激应答以及病毒感染过程中也发挥重要作用。PPIA的主要作用位点包括细胞质、细胞核以及细胞外空间,其表达产物可通过分泌形式参与细胞间通讯。突变或异常表达可能影响其酶活性或与其他蛋白的相互作用,导致功能紊乱。例如,PPIA突变可能影响其与HIV-1衣壳蛋白的结合,从而干扰病毒复制。PPIA过表达与多种疾病相关,包括癌症、心血管疾病和炎症性疾病,其高表达可能促进肿瘤细胞增殖、迁移和侵袭,或加剧炎症反应。相反,PPIA表达降低可能影响蛋白质的正确折叠,导致细胞功能异常,甚至凋亡。在基因家族中,亲环素家族成员(如PPIB、PPIC等)均具有PPIase活性,但组织分布和功能存在差异。PPIA作为该家族中最广泛研究的成员,其功能多样性使其成为疾病治疗(如免疫抑制、抗病毒和抗肿瘤)的潜在靶点。

This gene encodes a member of the peptidyl-prolyl cis-trans isomerase (PPIase) family. PPIases catalyze the cis-trans isomerization of proline imidic peptide bonds in oligopeptides and accelerate the folding of proteins. The encoded protein is a cyclosporin binding-protein and may play a role in cyclosporin A-mediated immunosuppression. The protein can also interact with several HIV proteins, including p55 gag, Vpr, and capsid protein, and has been shown to be necessary for the formation of infectious HIV virions. Multiple pseudogenes that map to different chromosomes have been reported. [provided by RefSeq, Jul 2008]

该基因编码的肽基脯氨酰顺反异构酶(PPIase)家族的一个成员。 PPIases催化寡脯氨酸酰亚胺肽键顺反异构化和加速的蛋白质的折叠。所编码的蛋白质是一个环孢菌素结合蛋白和在环孢菌素A介导的免疫抑制可以发挥作用。该蛋白还可以与若干HIV蛋白,包括P55的gag,Vpr基因和衣壳蛋白相互作用,并已被证明是必要的感染性的HIV病毒体的形成。已经报道了映射到不同的染色体的多个假。 [由RefSeq的,2008年7月提供]
