Function |
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). {ECO:0000250}.

Subcellular Location |
Isoform S-CaBP1: Cytoplasm, cell cortex. Cell membrane {ECO:0000305}; Lipid-anchor {ECO:0000305}. Note=S- CaBP1 is localized at or near the plasma membrane.
|
Tissue Specificity |
Retina and brain. Somatodendritic compartment of neurons. Calbrain was found exclusively in brain where it is abundant in the hippocampus, habenular area in the epithalamus and in the cerebellum.
