Biochem/physiol Actions

Calcium binding protein 1 is a protein encoded by the CABP1 gene in humans and belongs to neuron-specific member of the calmodulin (CaM) superfamily. It is a 19.4kDa protein of the EF-hand superfamily that modulates the activity of Ca2+ channels in the brain and retina. CABP1 helps in regulating the Ca2+ -dependent activity of inositol 1,4,5-triphosphate receptors (InsP3Rs) and various voltage-gated Ca2+ channels. CaBP1 interacts with cytosolic N- and C-terminal domains and blunts Ca2+-dependent inactivation. It may regulate Ca2+-dependent activity of InsP3Rs by promoting structural contacts between the suppressor and core domains.

CaBP1 is a Ca(2+)-binding protein that regulates the gating of voltage-gated (Ca(V)) Ca(2+) channels. In the Ca(V)1.2 channel α(1)-subunit (α(1C)), CaBP1 interacts with cytosolic N- and C-terminal domains and blunts Ca(2+)-dependent inactivation. To clarify the role of the α(1C) N-terminal

Calcium-binding protein 1 (CaBP1), a neuron-specific member of the calmodulin (CaM) superfamily, modulates Ca2+-dependent activity of inositol 1,4,5-trisphosphate receptors (InsP3Rs). Here we present NMR structures of CaBP1 in both Mg2+-bound and Ca2+-bound states and their structural interaction with InsP3Rs. CaBP1
