ATP1A1 (human)

Overview ATP1A1 the catalytic component of the active enzyme, which catalyzes the hydrolysis of ATP coupled with the exchange of Na and K ions across the plasma membrane. This action creates the electrochemical gradient of Na and K, providing the energy for active transport of various nutrients. Two splice-variant isoforms have been described. Note: This description may include information from UniProtKB. Protein type: Membrane protein, integral; EC 3.6.3.9; Hydrolase Cellular Component: Golgi apparatus; membrane; basolateral plasma membrane; endoplasmic reticulum; integral to membrane; plasma membrane; melanosome; sodium:potassium-exchanging ATPase complex; sarcolemma Molecular Function: 4-nitrophenylphosphatase activity; protein binding; metal ion binding; chaperone binding; sodium:potassium-exchanging ATPase activity; ATP binding Biological Process: response to drug; negative regulation of heart contraction; regulation of blood pressure; ATP biosynthetic process; positive regulation of striated muscle contraction; regulation of sodium ion transport; positive regulation of heart contraction; transmembrane transport; regulation of the force of heart contraction; negative regulation of glucocorticoid biosynthetic process Reference #:  P05023 (UniProtKB) Alt. Names/Synonyms: AT1A1; ATP1A1; ATPase, Na+/K+ transporting, alpha 1 polypeptide; MGC3285; MGC51750; Na(+)/K(+) ATPase alpha-1 subunit; Na+, K+ ATPase alpha subunit; Na+/K+ ATPase 1; Na, K-ATPase, alpha-A catalytic polypeptide; Na,K-ATPase alpha-1 subunit; Na,K-ATPase catalytic subunit alpha-A protein; sodium pump 1; Sodium pump subunit alpha-1; sodium-potassium-ATPase, alpha 1 polypeptide; Sodium/potassium-transporting ATPase subunit alpha-1 Gene Symbols: ATP1A1 Molecular weight: 112,896 Da Basal Isoelectric point: 5.33  Predict pI for various phosphorylation states Protein-Specific Antibodies or siRNAs from Cell Signaling Technology®
