ATP1A1
ATP1A1 (Sodium/potassium-transporting ATPase subunit alpha-1) is a gene that drives cell growth when it is altered. The public catalogues list it as a drug target and an oncogene driver, and clinical evidence ties its variants to diagnosis, prognosis or drug response. Tied to Breast cancer, Gastric & gastro-oesophageal junction cancer and Colorectal cancer. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.
Biology
Catalytic subunit of the Na(+)/K(+)-ATPase pump that hydrolyses ATP to exchange ions across the plasma membrane, exporting 3 Na(+) and importing 2 K(+) per cycle against electrochemical gradients. It undergoes ATP-driven conformational changes that allow alternating binding and release of Na(+) and K(+) ions across the membrane. This process maintains essential Na(+) and K(+) gradients for membrane potential and cellular function. Could also be part of an osmosensory signalling pathway that senses body-fluid sodium levels and controls salt intake behaviour as well as voluntary water intake to regulate sodium homeostasis. Location: Cell membrane; Basolateral cell membrane; Cell membrane, sarcolemma; Cell projection, axon (UniProt). Locus 1p13.1 (HGNC).
