CACNB3 (Calcium Voltage-Gated Channel Subunit Beta 3) is a gene that encodes a protein which is part of the voltage-gated calcium channel complex. These channels are crucial for the regulation of calcium ions in various cell types, particularly in excitable tissues such as the heart and nervous system. The protein encoded by CACNB3 is a beta subunit that assists in the proper functioning of calcium channels by modulating their activity and trafficking to the cell membrane.
