ATP2B1 - ATPase plasma membrane Ca2+ transporting 1 Gene
Also Known as MRD66; PMCA1; PMCA1kb
Species: Homo sapiens
About ATP2B1
This gene has 11 transcripts (splice variants), 195 orthologues, 21 paralogues and is associated with 1 phenotype. Ubiquitous expression in brain (RPKM 34.3), bone marrow (RPKM 16.4) and 23 other tissues.
Summary
The protein encoded by this gene belongs to the family of P-type primary ion transport ATPases characterized by the formation of an aspartyl phosphate intermediate during the reaction cycle. These Enzymes remove bivalent calcium ions from eukaryotic cells against very large concentration gradients and play a critical role in intracellular calcium homeostasis. The mammalian plasma membrane calcium ATPase isoforms are encoded by at least four separate genes and the diversity of these Enzymes is further increased by alternative splicing of transcripts. The expression of different isoforms and splice variants is regulated in a developmental, tissue- and cell type-specific manner, suggesting that these pumps are functionally adapted to the physiological needs of particular cells and tissues. This gene encodes the plasma membrane calcium ATPase isoform 1. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]
