== Function ==
[https://www.uniprot.org/uniprot/CABP1_HUMAN CABP1_HUMAN] 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 resulting in an opposit effects on channel function. Suppresses the calcium-dependent inactivation of CACNA1D (By similarity). Inhibits TRPC5 channels. Prevents NMDA receptor-induced cellular degeneration (By similarity).<ref>PMID:11865310</ref> <ref>PMID:14570872</ref> <ref>PMID:15140941</ref> <ref>PMID:15980432</ref> <ref>PMID:15895247</ref>
