Anti-NAC1 antibodies enable researchers to detect and measure the NAC1 antigen in biological samples. This target is a reported synonym of the SCN1A gene, which encodes sodium voltage-gated channel alpha subunit 1. This protein is known to function in cellular localization and the transport of ions, among other biological roles. The human version of NAC1 has a canonical amino acid length of 2009 residues and a protein mass of 229 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the cell membrane of cells. NAC1 is a member of the Sodium channel (TC 1.A.1.10) protein family.
