ATP2B1. also known as Plasma Membrane Calcium-Transporting ATPase 1 (PMCA1), is a member of the P-type ATPase superfamily responsible for maintaining calcium homeostasis in eukaryotic cells. Encoded by the ATP2B1 gene in humans, this enzyme utilizes energy from ATP hydrolysis to actively transport calcium ions (Ca²⁺) across the plasma membrane against their concentration gradient, thereby regulating intracellular Ca²⁺ levels. As the most ubiquitously expressed isoform among four PMCA subtypes (PMCA1-4), ATP2B1 is critical for cellular processes such as signal transduction, neurotransmitter release, and muscle contraction. Structurally, it contains 10 transmembrane domains, cytosolic ATP-binding and phosphorylation sites, and a calmodulin-binding autoinhibitory domain that modulates its activity in response to elevated Ca²⁺.
Dysregulation of ATP2B1 has been linked to pathological conditions, including hypertension, cardiovascular diseases, and neurodevelopmental disorders. Genome-wide association studies highlight ATP2B1 polymorphisms as susceptibility factors for blood pressure regulation. Recombinant ATP2B1. produced via heterologous expression systems like mammalian or insect cells, enables detailed biochemical and structural studies, aiding drug discovery and mechanistic insights. Recent research also explores its potential as a therapeutic target for calcium-related disorders or biomarker for disease prognosis. Despite its physiological importance, tissue-specific regulatory mechanisms and post-translational modifications of ATP2B1 warrant further investigation to fully elucidate its roles in health and disease.
