Previous GeneCards Identifiers for PKD1 Gene
This gene encodes a member of the polycystin protein family. The encoded glycoprotein contains a large N-terminal extracellular region, multiple transmembrane domains and a cytoplasmic C-tail. It is an integral membrane protein that functions as a regulator of calcium permeable cation channels and intracellular calcium homoeostasis. It is also involved in cell-cell/matrix interactions and may modulate G-protein-coupled signal-transduction pathways. It plays a role in renal tubular development, and mutations in this gene cause autosomal dominant polycystic kidney disease type 1 (ADPKD1). ADPKD1 is characterized by the growth of fluid-filled cysts that replace normal renal tissue and result in end-stage renal failure. Splice variants encoding different isoforms have been noted for this gene. Also, six pseudogenes, closely linked in a known duplicated region on chromosome 16p, have been described.

GeneCards Summary for PKD1 Gene
PKD1 (Polycystic Kidney Disease 1 (Autosomal Dominant)) is a Protein Coding gene. Diseases associated with PKD1 include polycystic kidney disease, adult type i and autosomal dominant polycystic kidney disease type 1 with tuberous sclerosis. Among its related pathways are Phospholipase-C Pathway and Organelle biogenesis and maintenance. GO annotations related to this gene include protein kinase binding and protein domain specific binding. An important paralog of this gene is PKD1L1.
UniProtKB/Swiss-Prot for PKD1 Gene
Involved in renal tubulogenesis (PubMed:12482949). Involved in fluid-flow mechanosensation by the primary cilium in renal epithelium (By similarity). Acts as a regulator of cilium length, together with PKD2 (By similarity). The dynamic control of cilium length is essential in the regulation of mechanotransductive signaling (By similarity). The cilium length response creates a negative feedback loop whereby fluid shear-mediated deflection of the primary cilium, which decreases intracellular cAMP, leads to cilium shortening and thus decreases flow-induced signaling (By similarity). May be an ion-channel regulator. Involved in adhesive protein-protein and protein-carbohydrate interactions.
