Elucidation of the normal function of the PKD-encoded polycystins and effects of their mutations in autosomal dominant polycystic kidney disease (ADPKD)

Autosomal dominant polycystic kidney disease (ADPKD) is the most common genetic disease inherited as a dominant trait occurring at a rate of 1:800 live births and affectring 500,000 people in US and 4-6 million world wide. 85-90 percent of cases are due to mutations in the PKD1 gene and 10-15 percent are due to mutations in PKD2. Studies in this laboratory are focused on determining the functions of the respective encoded proteins, polycystin-1 and polycystin-2 in their normal and mutant forms associated with renal development and cystic disease. Previous studies have determined that polycystin-1 is developmentally regulated and highly expressed in fetal kidney ureteric bud epithelia with a role in cell adhesion, migration and tubulogenesis. Polycystin-1 forms multiprotein complexes with polycystin-2 and multiple focal adhesion protein components at the basal epithelial cell membrane of fetal cells and with E-cadherin and -catenin at the apical-lateral junctions of adult renal epithelia. In addition, polycystins have been localized to the non-motile central cilia of renal collecting ducts. The intracellular C-terminal domain of polycystin-1 is phosphorylated at several tyrosine and serine sites by focal adhesion kinase (FAK), c-src, protein kinase A(PKA), and protein kinase X (PRKX). In addition a proline -rich SH3 and putative WW site have been identified. The roles of phosphorylation and protein binding motifs in the regulation of normal and mutant intracellular signaling via FAK/MAP kinase/AP-1 or -catenin/TCF pathways is under study. Multiple reporter (EGFP or FLAG) wild-type, truncation and point mutant C-terminal domain PKD1 constructs are used for transfection analysis in conditionally immortalized renal epithelial cell lines derived from human fetal and adult normal proximal, thick ascending limb and collecting tubules as well as cyst lining epithelia from ADPKD and ARPKD kidneys. Assays include polarization of EGFR and NaK-ATPase; matrix adhesion, migration, 3-dimensional tubulogenesis in collagen gels and development in organ culture.
