Autosomal dominant polycystic kidney disease (ADPKD) is the most common inherited cause of kidney failure and affects up to 12 million people worldwide. Germline mutations in two genes, PKD1 or PKD2, account for almost all patients with ADPKD. The ADPKD proteins, polycystin-1 (PC1) and polycystin-2 (PC2), are regulated by post-translational modifications (PTM), with phosphorylation, glycosylation and proteolytic cleavage being the best described changes. A few PTMs have been shown to regulate polycystin trafficking, signalling, localisation or stability and thus their physiological function. A key challenge for the future will be to elucidate the functional significance of all the individual PTMs reported to date. Finally, it is possible that site-specific mutations that disrupt PTM could contribute to cystogenesis although in the majority of cases, confirmatory evidence is awaited.

多囊蛋白的翻译后修饰。

常染色体显性多囊肾病 (ADPKD) 是肾功能衰竭最常见的遗传原因,影响全球多达 1200 万人。PKD1 或 PKD2 这两个基因的种系突变几乎可以解释所有 ADPKD 患者。ADPKD 蛋白 polycystin-1 (PC1) 和 polycystin-2 (PC2) 受翻译后修饰 (PTM) 的调控,其中磷酸化、糖基化和蛋白水解切割是描述得最清楚的变化。一些 PTM 已被证明可以调节多囊蛋白的运输、信号传递、定位或稳定性,从而调节它们的生理功能。未来的一个关键挑战将是阐明迄今为止报告的所有单个 PTM 的功能意义。最后,
