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.
