ACP2(酸性磷酸酶2,Acid Phosphatase 2)是一种溶酶体酶,属于酸性磷酸酶家族(Acid Phosphatase Family),该家族成员主要功能是催化磷酸单酯的水解反应,参与磷酸代谢。ACP2在溶酶体中高度表达,负责分解细胞内的磷酸化合物,如核苷酸、磷脂和糖磷酸酯,从而维持细胞内磷酸稳态。其表达产物是一种糖蛋白,依赖锰离子(Mn²⁺)作为辅因子发挥最佳活性。ACP2的主要作用位点是溶酶体,但也可能存在于其他酸性细胞器中。若ACP2发生功能丧失突变,可能导致溶酶体贮积症(Lysosomal Storage Disorders),例如一种罕见的神经退行性疾病——脑腱黄瘤病(Cerebrotendinous Xanthomatosis, CTX)的部分病例与ACP2缺陷相关,表现为胆固醇代谢异常和神经系统损伤。此外,ACP2表达异常还与某些癌症(如前列腺癌、乳腺癌)的进展相关,可能通过影响细胞凋亡或增殖信号通路发挥作用。若ACP2过表达,可能加剧溶酶体功能紊乱,导致细胞毒性或异常自噬;而表达降低则可能引起底物累积,引发代谢障碍。ACP2基因家族(包括ACP1、ACP3等)的共性是均含有保守的磷酸酶结构域,偏好酸性pH环境,并参与磷酸基团的移除反应。目前“酸性磷酸酶2”的中文译名较为统一,但需注意其与前列腺特异性酸性磷酸酶(PAP)等家族成员区分。研究显示,ACP2可能通过调控溶酶体功能间接影响mTOR信号通路(控制细胞生长的关键通路)或炎症因子释放,但其具体机制仍需进一步探索。

This gene encodes the beta subunit of lysosomal acid phosphatase (LAP). LAP is chemically and genetically distinct from red cell acid phosphatase. The encoded protein belongs to a family of distinct isoenzymes which hydrolyze orthophosphoric monoesters to alcohol and phosphate. LAP-deficiencies in mice cause multiple defects including bone structure alterations, lysosomal storage defects in the kidneys and central nervous system, and an increased tendency towards seizures. An enzymatically-inactive allele of LAP in mice exhibited a more severe phenotype than the null allele, and defects included cerebellum abnormalities, growth retardation, hair-follicle abnormalities, and an ataxia-like phenotype. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Oct 2014]

该基因编码溶酶体酸性磷酸酶(LAP)的β亚基。 LAP是化学和红细胞酸性磷酸酶基因不同。所编码的蛋白质属于家族,其水解正单酯为醇及磷酸不同同工酶。在小鼠中的LAP-缺陷导致多种缺陷,包括骨结构的改变,溶酶体贮积缺陷在肾脏和中枢神经系统,并朝向癫痫倾向增加。在小鼠中的LAP的酶促惰性等位基因表现出更严重的表型比无效等位基因,和缺陷包括小脑异常,生长迟缓,毛囊异常,共济失调,样表型。在多个转录剪接变异体导致编码不同亚型。 [由RefSeq的,2014年10月提供]
