The polycystic kidney disease 1 (PKD1) gene encodes a novel protein with multiple cell recognition domains

Abstract
Characterization of the polycystic kidney disease 1 (PKD1) gene has been complicated by genomic rearrangements on chromosome 16. We have used an exon linking strategy, taking RNA from a cell line containing PKD1 but not the duplicate loci, to clone a cDNA contig of the entire transcript. The transcript consists of 14,148 bp (including a correction to the previously described C terminus), distributed among 46 exons spanning 52 kb. The predicted PKD1 protein, polycystin, is a glycoprotein with multiple transmembrane domains and a cytoplasmic C-tail. The N–terminal extracellular region of over 2,500 aa contains leucine–rich repeats, a C–type lectin, 16 immunoglobulin–like repeats and four type III fibronectin–related domains. Our results indicate that polycystin is an integral membrane protein involved in cell–cell/matrix interactions.
