在人类中，atp结合盒（abc）跨膜转运蛋白家族至少有48个基因和7个基因亚家族。该基因是ABC基因亚家族a（ABCA）的成员abca家族中的基因通常编码几千个氨基酸。与其他abc跨膜转运蛋白一样，该蛋白具有12个或更多的跨膜α螺旋结构域，这些结构域可能排列成具有多个底物结合位点的单个中央腔室。它也被预测有两个大的胞外结构域和两个核苷酸结合结构域，这是abca蛋白的典型特征。已经描述了选择性剪接变体，但尚未证明其生物学有效性。[由RefSeq提供，2009年3月]
In human, the ATP-binding cassette (ABC) family of transmembrane transporters has at least 48 genes and 7 gene subfamilies. This gene is a member of ABC gene subfamily A (ABCA). Genes within the ABCA family typically encode several thousand amino acids. Like other ABC transmembrane transporter proteins, this protein has 12 or more transmembrane alpha-helix domains that likely arrange to form a single central chamber with multiple substrate binding sites. It is also predicted to have two large extracellular domains and two nucleotide binding domains as is typical for ABCA proteins. Alternative splice variants have been described but their biological validity has not been demonstrated.[provided by RefSeq, Mar 2009]
