Anti-ATP1B4 antibodies are used in the immunodetection of the protein ATPase Na+/K+ transporting family member beta 4. In humans, the canonical protein has a reported length of 357 amino acid residues and a mass of 41.6 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. It is reported to be highly expressed in skeletal muscle and at a lower level in the heart. A member of the X(+)/potassium ATPases subunit beta protein family, ATP1B4 is believed to act as a transcriptional coregulator during muscle development through its interaction with SNW1. Synonyms for this target antigen include ATPase, Na+/K+ transporting, beta 4 polypeptide, BetaM, Na,K-ATPase beta m-subunit, X,K-ATPase beta-m subunit, x/potassium-transporting ATPase subunit beta-m, and protein ATP1B4. ATP1B4 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Western Blot is a widely used application for the ATP1B4 antibodies listed below. In addition, ELISA is also a common application.
