Gene: ATP2A1 (ATPase sarcoplasmic/endoplasmic reticulum Ca2+ transporting 1) Homo sapiens
Symbol: ATP2A1
Name: ATPase sarcoplasmic/endoplasmic reticulum Ca2+ transporting 1
Description: Exhibits calcium ion binding activity; calcium transmembrane transporter activity, phosphorylative mechanism; and protein homodimerization activity. Involved in several processes, including cellular calcium ion homeostasis; maintenance of mitochondrion location; and regulation of striated muscle contraction. Localizes to the H zone; I band; and endoplasmic reticulum membrane. Implicated in Brody myopathy.
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: ATP2A; ATPase, Ca++ transporting, cardiac muscle, fast twitch 1; calcium pump 1; calcium-transporting ATPase sarcoplasmic reticulum type, fast twitch skeletal muscle isoform; endoplasmic reticulum class 1/2 Ca(2+) ATPase; sarcoplasmic/endoplasmic reticulum calcium ATPase 1; SERCA1; SR Ca(2+)-ATPase 1
