The function of ENSG00000153956 (CACNA2D1, calcium voltage-gated channel auxiliary subunit alpha2delta 1) is as follows. The alpha-2/delta subunit of voltage-dependent calcium channels regulates calcium current density and activation/inactivation kinetics of the calcium channel (PubMed:35293990). Plays an important role in excitation-contraction coupling (By similarity). {ECO:0000250, ECO:0000269|PubMed:35293990}.
