Facts about Calcium-binding protein 1.
Enhances inactivation and doesn't support calcium-dependent facilitation of voltage-dependent P/Q-type calcium channels (PubMed:11865310). Causes calcium-dependent facilitation and inhibits inactivation of L-type calcium channels by binding to the same sites as calmodulin from the C-terminal domain of CACNA1C, but has an opposite effect on channel function (PubMed:15140941).

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.
Cytoplasm, cytoskeleton. Cytoplasm, perinuclear region. Cell membrane; Lipid-anchor; Cytoplasmic side. Golgi apparatus. Cell junction, synapse, postsynaptic density. L-CaBP1 is associated most likely with the cytoskeletal structures, whereas S-CaBP1 is localized at or near the plasma membrane.; [Isoform L-CaBP1]: Cytoplasm, cytoskeleton. L-CaBP1 is associated most likely with the cytoskeletal structures.; [Isoform S-CaBP1]: Cytoplasm, cell cortex. Cell membrane; Lipid-anchor. S-CaBP1 is localized at or near the plasma membrane.
