ATP7B基因编码一种铜转运P型ATP酶,属于P型ATP酶家族中的重金属转运ATP酶亚家族。这个基因主要在肝脏中表达,其编码的蛋白质负责将铜离子从肝细胞转运到胆汁中排出体外,并参与铜蓝蛋白的合成。ATP7B蛋白具有典型的P型ATP酶结构域,包括跨膜区、ATP结合区和磷酸化区,通过水解ATP提供的能量实现铜离子的跨膜转运。当ATP7B基因发生突变时,会导致铜离子在肝脏和其他组织中异常积累,引发威尔逊病(Wilson disease),这是一种常染色体隐性遗传的铜代谢障碍疾病。常见的突变包括H1069Q、R778L等,这些突变会影响蛋白质的折叠、定位或功能。ATP7B基因过表达理论上可能增强铜的排泄,但实际研究中很少观察到这种情况;而表达降低或功能缺失则会导致铜代谢紊乱。在威尔逊病患者中,铜的积累会损害肝脏、大脑(特别是基底节)、角膜(形成Kayser-Fleischer环)和肾脏等器官。ATP7B与另一个铜转运ATP酶ATP7A属于同一基因家族,ATP7A负责肠道铜吸收和跨细胞转运,这两个基因共同维持体内铜的平衡。P型ATP酶家族的共同特点是都能水解ATP并利用释放的能量进行离子或分子的跨膜转运,包括钠钾泵、钙泵等。ATP7B基因的检测对于威尔逊病的诊断和携带者筛查具有重要意义,早期诊断和青霉胺等药物治疗可以显著改善患者预后。

This gene is a member of the P-type cation transport ATPase family and encodes a protein with several membrane-spanning domains, an ATPase consensus sequence, a hinge domain, a phosphorylation site, and at least 2 putative copper-binding sites. This protein functions as a monomer, exporting copper out of the cells, such as the efflux of hepatic copper into the bile. Alternate transcriptional splice variants, encoding different isoforms with distinct cellular localizations, have been characterized. Mutations in this gene have been associated with Wilson disease (WD). [provided by RefSeq, Jul 2008]

该基因是P型阳离子运输ATP酶家族的成员,并编码具有几个跨膜结构域的蛋白,ATP酶共有序列,铰链结构域,磷酸化位点,和至少2个推定的铜结合网站。该蛋白质的功能作为单体,出口铜出细胞,如肝铜的流出进入胆汁。备用转录剪接变体,编码具有不同细胞定位不同同种型,已经表征。在这种基因突变与Wilson病(WD)相关联。 [由RefSeq的,2008年7月提供]
