Function

Also known as PC2. Mutation causes autosomal domi nt PKD. Dimerizes with PKD1 to form a channel in the ciliary membrane (20392267) and mediate transduction of an extracellular mechanical stimulus into a Ca2+ sig ling response involved in the differentiation of kidney tubular epithelial cells (12514735, 26788466). PC2 enhances calcium release from the ER by stimulating the activity of the IP3 receptor (26788466). Required for the asymmetric localization of Vangl2 and involved in the establishment of the asymmetric positioning of pla r cell polarity proteins (26245976).
