This gene encodes one of the SERCA Ca(2+)-ATPases, which are intracellular pumps located in the sarcoplasmic or endoplasmic reticula of muscle cells. This enzyme catalyzes the hydrolysis of ATP coupled with the translocation of calcium from the cytosol to the sarcoplasmic reticulum lumen, and is involved in calcium sequestration associated with muscular excitation and contraction. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]
GeneCards Summary for ATP2A3 Gene
ATP2A3 (ATPase Sarcoplasmic/Endoplasmic Reticulum Ca2+ Transporting 3) is a Protein Coding gene. Diseases associated with ATP2A3 include Darier-White Disease and Atrophic Muscular Disease. Among its related pathways are Signaling by GPCR and Spinocerebellar ataxia. Gene Ontology (GO) annotations related to this gene include nucleotide binding and calcium-transporting ATPase activity. An important paralog of this gene is ATP2A2.
UniProtKB/Swiss-Prot Summary for ATP2A3 Gene
This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the transport of calcium. Transports calcium ions from the cytosol into the sarcoplasmic/endoplasmic reticulum lumen. Contributes to calcium sequestration involved in muscular excitation/contraction.
Ca2+-ATPases function to maintain a low cytoplasmic concentration of Ca2+ ions. They are high affinity, low capacitance transporters and complement the actions of the low affinity, high capacitance Na+/Ca2+ exchanger. Ca2+-ATPases are P-type ATPases.
