MGI:1195264Mutation of this locus results in renal absorption defects and cystine urolithiasis. Homozygous mutant mice serve as a mouse model for human cystinuria type I.
Slc3a1基因,也称为溶质载体家族3成员1(Solute Carrier Family 3 Member 1),编码了一种与系统bo,+氨基酸转运蛋白相关的蛋白质。这种蛋白质在肾脏近端小管中负责氨基酸的重吸收,特别是在氨基酸转运过程中发挥关键作用。Slc3a1基因的突变与胱氨酸尿症有关,这是一种遗传性疾病,其特征是尿液中胱氨酸浓度升高,导致肾结石的形成。胱氨酸尿症是由于肾脏近端小管中氨基酸转运蛋白的缺陷,导致胱氨酸和其他二价氨基酸(如赖氨酸、鸟氨酸和精氨酸)的重吸收受损,从而导致这些氨基酸在尿液中的过量积累和结晶。
