Protein Structure
UniProt Annotation
Function The alpha-2/delta subunit of voltage-dependent calcium channels regulates calcium current density and activation/inactivation kinetics of the calcium channel. Acts as a regulatory subunit for P/Q-type calcium channel (CACNA1A), N-type (CACNA1B), L-type (CACNA1C OR CACNA1D) but not T-type (CACNA1G) (By similarity). {ECO:0000250}.
Subcellular Localization Membrane {ECO:0000305}; Single-pass type I membrane protein {ECO:0000305}.
Disease Associations
Tissue Specificity Only detected in brain. Not present in lung, testis, aorta, spleen, jejunum, ventricular muscle and kidney (at protein level). According to PubMed:11687876, it is brain- specific, while according to PubMed:11245980, it is widely expressed. {ECO:0000269PubMed:11687876}.
