General Information | Comment | Organism |

physiological function | enzyme overexpression decreases [Ca2+] in the cytosol, the endoplasmic reticulum (ER), and the mitochondria and activates the inositol-requiring transmembrane kinase and endonuclease 1alpha-spliced X-box binding protein 1 but inhibits the PRKR-like ER kinase-eIF2alpha and the activation of transcription factor 6-immunoglobulin heavy chain binding protein pathways of the ER-unfolded protein response. Isoform PMCA2 overexpression depletes cytosolic, ER and mitochondrial Ca2+ stores and induces apoptosis via the mitochondrial pathway. PMCA2-overexpressing cells also display increased levels of caspase-3 cleavage | Rattus norvegicus |
