A second gene for autosomal dominant polycystic kidney disease was identified by positional cloning. Nonsense mutations in this gene (PKD2) segregated with the disease in three PKD2 families. The predicted 968-amino acid sequence of the PKD2 gene product has six transmembrane spans with intracellular amino- and carboxyl-termini. The PKD2 protein has amino acid similarity with PKD1, the Caenorhabditis elegans homolog of PKD1, and the family of voltage-activated calcium (and sodium) channels, and it contains a potential calcium-binding domain.
通过定位克隆鉴定出了常染色体显性多囊肾病的第二个基因。该基因(PKD2)中的无义突变在三个PKD2家族中与疾病共分离。PKD2基因产物预测的968个氨基酸序列有六个跨膜结构域,其氨基末端和羧基末端位于细胞内。PKD2蛋白与PKD1、秀丽隐杆线虫PKD1的同源物以及电压激活钙(和钠)通道家族在氨基酸上具有相似性,并且它含有一个潜在的钙结合结构域。
