SERCA is the abbreviation for the sarco/endoplasmic reticulum Ca2+ ATPase pump. It pumps calcium ions into the sarcoplasmic reticulum as well as in the endoplasmic reticulum[1]. It is a regulator of the OFF mechanisms designed to keep our intracellular calcium ion concentration low[2]. SERCA pumps are located on the membrane, they eventually get saturated along with the PMCA pumps by a rising level of calcium ions, and then only do the mitochondria and Na/Ca exchanger begin to work.
Inhibitors
SERCA pumps are inhibited by more than 72 compounds[3], however, the most commonly used ones are thapsigargin[4], 2,5-Di(tert-butyl)-1,4-benzohydroquinone[5] and cyclopiazonic acid[6].
