These ATPase, Na+/K+ transporting, beta 4 polypeptide ELISA kits are immunodetection tools for measuring specific protein levels in biological samples. ATPase, Na+/K+ transporting, beta 4 polypeptide is an alias of the human ATP1B4 gene, which encodes the protein, ATPase Na+/K+ transporting family member beta 4. Notably, ATPase, Na+/K+ transporting, beta 4 polypeptide is known to play a role in the transport of ions and the regulation of transcription, among other functions. The ATP1B4 protein is 357 amino acid residues in length and 41.6 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the nucleus of the cell. In terms of tissue specificity, it is reported to be highly expressed in skeletal muscle and at a lower level in heart. Other names for this target antigen include protein ATP1B4 and ATPase, Na+/K+ transporting, beta 4 polypeptide.
