ALPI
碱性磷酸酶(ALP或AKP、AP)是广泛分布于人体肝脏、骨骼、肠、肾和胎盘等组织的单磷脂水解酶。这种酶能催化核酸分子脱掉5’磷酸基团,从而使DNA或RNA片段的5’-P末端转换成5’-OH末端。
本身是一种膜结合金属糖蛋白,由两个亚单位组成,作为同源二聚体酶,包括四种同工酶,分别是组织非特异性AP(TNAP)、肠型AP(IAP)、胎盘型AP(PLAP)和类PLAP。
TNAP主要在肝脏、肾脏和骨组织中表达,即肝/骨/肾型AP。其中骨型AP是成骨细胞的一种细胞外酶,能被释放到血液循环中,在机体的生理功能主要是在成骨过程中水解磷酸酯,为羟磷灰石的沉积提供必需的磷酸,同时水解焦磷酸盐,解除其对骨盐形成的抑制作用,有利于成骨过程。
IAP、PLAP和类PLAP为组织特异性AKP。IAP是一种能水解单磷酸酯的刷状缘蛋白,可进一步分为胎儿IAP和成人IAP。该蛋白由肠黏膜上皮微绒毛、肾近曲小管远侧端和子宫分泌,胎儿IAP又称笠原同工酶,它作为肿瘤标志物,出现于肝癌及其它器官发生肿瘤的病人血清中。PLAP主要由孕8周后的胎盘合胞体滋养层细胞微绒毛分泌,肺脏、卵巢、子官、胃肠道及其它脏器也分泌少量的PLAP,PLAP在人体的生理功能主要是参与细胞膜对物质的主动运输及钙、磷代谢,提供胎儿生长发育所需营养,对胎儿的生长发育起着重要作用,动态观察胎盘型碱性磷酸酶活性可作为妊娠的一项指标。类PLAP又称Nagao同工酶,本质是精原细胞AP(GCAP),是一种肿瘤标记物,出现于多种癌症中,如精原细胞瘤、卵巢癌等。
