GeneID: 222

Description:
The PKD1L2 gene encodes polycystin-1L2 (PC1L2), member of the polycystin-1-like (PC1L) sub-family of proteins. Polycystin-1 is a large integral membrane glycoprotein containing 11 transmembrane segments with extracellular N-terminal and intracellular C-terminal domains. The N-terminal region contains a number of adhesive domains (e.g. leucine-rich repeats, a C-type lectin domain, and an LDL-A-like domain) that facilitate a wide range of cell-cell or cell-matrix interactions. The C-terminal region includes a coiled-coil domain known to interact with and regulate the function of polycystin-2 (PC2), a protein that behaves as a calcium-activated cation channel. PC1L2 contains an ion transport domain rather than a coiled-coil domain and has several putative phosphorylation sites that may be involved in the regulation of downstream signalling. All PC1-like sub-family proteins contain a GPS domain, can bind to specific Gα protein subunits and likely function as G-protein coupled receptors. PC1L2 may function as an ion-channel regulator. The PKD1L2 gene is highly expressed in the kidney and is a suspected modifier of polycystic kidney disease. It is also expressed in the heart and has been implicated in normal cardiac development and function. Alternative splicing results in multiple transcript variants. This gene appears to be a polymorphic pseudogene in humans, where some individuals contain a non-functional allele. A polymorphism in this gene associated with glomerular filtration rate in pediatric patients with sickle cell disease.
