Anti-SCN2B antibodies are used in the immunodetection of the protein sodium voltage-gated channel beta subunit 2. In humans, the canonical protein has a reported length of 215 amino acid residues and a mass of 24.3 kDa. Its subcellular localization is in the membrane. It is reported to have brain specific expression. A member of the Sodium channel auxiliary subunit SCN2B (TC 8.A.17) protein family, it is known to be involved with chemical synaptic transmission and nervous system development. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include sodium channel subunit beta-2, neuronal voltage-gated sodium channel beta 2 subunit, sodium channel, voltage gated, type II beta subunit, and ATFB14.
