Anti-Cav3.3 antibodies enable researchers to detect and measure the Cav3.3 antigen in biological samples. This target is a reported synonym of the CACNA1I gene, which encodes calcium voltage-gated channel subunit alpha1 I. This protein is known to function in the transport of ions and signal transduction pathways, among other biological roles. The human version of Cav3.3 has a canonical amino acid length of 2223 residues and a protein mass of 245.1 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the membrane of cells. This target antigen may also be known as NEDSIS.
