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. Plays an important role in excitation-contraction coupling (By similarity). {ECO:0000250}.

Subcellular Localization

Membrane {ECO:0000305}; Single-pass type I membrane protein {ECO:0000305}.

Disease Associations

Tissue Specificity

Isoform 1 is expressed in skeletal muscle. Isoform 2 is expressed in the central nervous system. Isoform 2, isoform 4 and isoform 5 are expressed in neuroblastoma cells. Isoform 3, isoform 4 and isoform 5 are expressed in the aorta. {ECO:0000269PubMed:1309651, ECO:0000269PubMed:8107964}.
