This gene encodes a protein that belongs to a subfamily of calcium binding proteins which share similarity to calmodulin. The protein encoded by this gene regulates the gating of voltage-gated calcium ion channels. This protein inhibits calcium-dependent inactivation and supports calcium-dependent facilitation of ion channels containing voltage-dependent L-type calcium channel subunit alpha-1C. This protein also regulates calcium-dependent activity of inositol 1,4,5-triphosphate receptors, P/Q-type voltage-gated calcium channels, and transient receptor potential channel TRPC5. This gene is predominantly expressed in retina and brain. Alternative splicing results in multiple transcript variants encoding disinct isoforms. [provided by RefSeq, Jul 2012]. * **UniProt Summary**: Modulates calcium-dependent activity of inositol 1,4,5- triphosphate receptors (ITPRs). Inhibits agonist-induced intracellular calcium signaling. Enhances inactivation and does not support calcium-dependent facilitation of voltage-dependent P/Q-type calcium channels. Causes calcium-dependent facilitation and inhibits inactivation of L-type calcium channels by binding to the same sites as calmodulin in the C-terminal domain of CACNA1C, but has an opposite effect on channel function. Suppresses the calcium-dependent inactivation of CACNA1D (By similarity). Inhibits TRPC5 channels. Prevents NMDA receptor-induced cellular degeneration (By similarity). {ECO:0000250, ECO:0000250|UniProtKB:O88751, ECO:0000269|PubMed:11865310, ECO:0000269|PubMed:14570872, ECO:0000269|PubMed:15140941, ECO:0000269|PubMed:15895247, ECO:0000269|PubMed:15980432}. |efhand| |negative regulation of protein import| |negative regulation of protein import into nucleus| |negative regulation of nucleocytoplasmic transport| |nuclear localization sequence binding| |negative regulation of protein localization to nucleus| |enzyme inhibitor activity| |negative regulation of intracellular protein transport| |regulation of protein import into nucleus| |regulation of protein import| |negative regulation of intracellular transport| |calcium-dependent protein binding| |regulation of nucleocytoplasmic transport| |negative regulation of cellular protein localization| |regulation of protein localization to nucleus| |cell cortex| |negative regulation of protein transport| |negative regulation of establishment of protein localization| |postsynaptic membrane| |visual perception| |sensory perception of light stimulus| |regulation of intracellular protein transport| |postsynaptic density| |regulation of intracellular transport| |cytoskeleton| |negative regulation of transport| |regulation of cellular protein localization| |cell junction| |Golgi membrane| |perinuclear region of cytoplasm| |regulation of protein transport| |calcium ion binding| |regulation of peptide transport| |regulation of establishment of protein localization| |negative regulation of catalytic activity| |regulation of cellular localization| |sensory perception| |regulation of protein localization| |negative regulation of molecular function| |nervous system process| |extracellular space| |regulation of transport| |system process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp247|UM0130462 0.025 to 0.035μM day4 R05 exp247]]|1.75| |[[:results:exp443|SNS-032 15μM R08 exp443]]|1.86| |[[:results:exp467|CAY10603 0.55μM R08 exp467]]|2.09| No correlation found to any other genes in chemogenomics.
