Calcium voltage-gated channel auxiliary subunit beta 3 (CACNB3)

Target
CACNB3
Molecular classification
Ion channel auxiliary subunit, Voltage-gated calcium channel subunit
01

Overview

Calcium voltage-gated channel auxiliary subunit beta 3 (CACNB3) is a regulatory beta subunit of the voltage-dependent calcium channels (primarily the L-type) that are essential for the proper function of excitable cells, such as neurons and muscle.
