ABC型有机阴离子转运蛋白 ABCA8 (EC 7.6.2.-) (ATP结合盒亚家族A成员8)

O94911

功能描述

[Isoform 1]: 催化ATP依赖的有机阴离子(如牛磺胆酸和硫酸雌酮)的输入 (PubMed:12379217)。在体外,也输入赭曲霉毒素A (PubMed:12379217)。也介导不依赖载脂蛋白的胆固醇外排,并在少突胶质细胞的鞘磷脂生成中发挥作用 (PubMed:23560799)。 {ECO:0000269|PubMed:12379217, ECO:0000269|PubMed:23560799}.; FUNCTION: [Isoform 3]: 催化ATP依赖的胆固醇和牛磺胆酸的外排 (PubMed:29300488)。与ABCA1的相互作用增强了向无脂APOA1的胆固醇外排,从而调节高密度脂蛋白胆固醇水平 (PubMed:28882873)。 {ECO:0000269|PubMed:28882873, ECO:0000269|PubMed:29300488}.

组织特异性

Widely expressed with higher expression in heart, skeletal muscle and liver (PubMed:12379217, PubMed:28882873, PubMed:29300488). Highly expressed in the superior frontal white matter and inferior temporal white matter (PubMed:12379217).
