Cacnb3 - calcium voltage-gated channel auxiliary subunit beta 3

Enables calcium channel regulator activity; protein kinase binding activity; and voltage-gated calcium channel activity. Contributes to high voltage-gated calcium channel activity. Involved in several processes, including calcium ion transport; regulation of ion transmembrane transport; and regulation of nervous system process. Located in apical plasma membrane. Part of L-type voltage-gated calcium channel complex. Orthologous to human CACNB3 (calcium voltage-gated channel auxiliary subunit beta 3). [provided by Alliance of Genome Resources, Apr 2022]
