【ALDH1A2】
醛脱氢酶1家族成员A2（Aldehyde dehydrogenase 1 family, member A2），简称为ALDH1A2，或称为视黄醛脱氢酶2（简写为RALDH2），是在人体内一种由ALDH1A2基因编码的酶。此蛋白为醛脱氢酶蛋白家族成员，是负责催化视黄酸到视黄醛的合成的酶。视黄酸是维生素A（即视黄醇）的活性衍生物，是一种旁分泌激素信号分子，主要作用于发育中的组织和成年组织中。对小鼠中类似基因的研究表明，这种酶和细胞色素CYP26A1同时确立局部胚胎组织中的视黄酸浓度，促进后部器官发育和防止脊柱裂。ALDH1A2基因已确认有三种可编码不同亚型蛋白的转录变异体。
