PKD DOMAIN 1 FROM HUMAN POLYCYSTEIN-1

Overview
Most cases of autosomal dominant polycystic kidney disease (ADPKD) are the result of mutations in the PKD1 gene. The PKD1 gene codes for a large cell-surface glycoprotein, polycystin-1, of unknown function, which, based on its predicted domain structure, may be involved in protein-protein and protein-carbohydrate interactions. Approximately 30% of polycystin-1 consists of 16 copies of a novel protein module called the PKD domain. Here we show that this domain has a beta-sandwich fold. Although this fold is common to a number of cell-surface modules, the PKD domain represents a distinct protein family. The tenth PKD domain of human and Fugu polycystin-1 show extensive conservation of surface residues suggesting that this region could be a ligand-binding site. This structure will allow the likely effects of missense mutations in a large part of the PKD1 gene to be determined.
Disease
Known disease associated with this structure: Polycystic kidney disease, adult type I OMIM:[601313]
