Cacnb1 - calcium channel, voltage-dependent, beta 1 subunit

Enables high voltage-gated calcium channel activity. Acts upstream of or within calcium ion transport and protein targeting to membrane. Located in T-tubule; presynapse; and sarcoplasmic reticulum. Part of voltage-gated calcium channel complex. Is expressed in several structures, including diaphragm; lower leg rest of mesenchyme; nervous system; skeletal musculature; and tail paraxial mesenchyme. Orthologous to human CACNB1 (calcium voltage-gated channel auxiliary subunit beta 1). [provided by Alliance of Genome Resources, Apr 2022]
