Function

CACNA1C, also called CaV1.2Serves as a modifier gene to cystic kidney phenotype. Plays an important role in Akt and Erk activities through cytosolic calcium and CaM kinase II. CaV1.2 might be a secondary calcium-permeable channel to the polycystins complex (24925129). CaV1.2 expression is regulated through Wnt signaling and plays an essential sensory role in primary cilia for cellular homeostasis (24700505). CaV1.2 knockdown had no effect on cilia length in wildtype cells but shortened cilia in Pkd1-/- and Pkd2-/- cells (PMID: 24925129). CaV1.2 is not required for cilia formation (PMID: 24700505)
