ATP dependent calcium pumps are responsible in part for the maintenance of low cytoplasmic free calcium concentrations. The ATP pumps that reside in intracellular organelles are encoded by a family of structurally related enzymes, termed the sarcoplasmic or endoplasmic reticulum calcium ATPases (SERCA). The SERCA2 gene is subject to tissue dependent processing which is responsible for the generation of SERCA2a muscle-specific isoform expressed in type I (slow) skeletal, cardiac and smooth muscle and the SERCA2b isoform expressed in all cell types. SERCA3 has been found to co-express with SERCA2b in platelets, mast cells, lymphoid cells, and epithelial cells. Due to this pattern of expression it is referred to as the non-muscle form of SERCA.
