This gene encodes one of the SERCA Ca(2+)-ATPases, which are intracellular pumps located in the sarcoplasmic or endoplasmic reticula of muscle cells.
Their homeothermy may also rely on SERCA2 and Ryanodine receptor 2 protein expression, which may have a cardioprotective effect.
Increased β-adrenergic stimulation reduces the association between SERCA and PLB by the phosphorylation of PLB by PKA.
For the calcium pump, see SERCA
It seems that, in addition to the calcium-transporting properties, SERCA1 generates heat in some adipocytes.

Elysia serca also bears great similarities to Elysia catulus (Gould, 1870), a species with a more northerly distribution, and Jensen (1983) considers that E. serca may be a subspecies or ecotype of E. catulus.
