UniProtKB accession:  P42532

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Reversibly inhibits the activity of ATP2A1/SERCA1 and ATP2A2/SERCA2 in sarcoplasmic reticulum by decreasing the apparent affinity of the ATPase for Ca(2+) (PubMed:23362265, PubMed:9575189). Also inhibits the activity of ATP2A3/SERCA3 (By similarity). Modulates calcium re-uptake during muscle relaxation and plays an important role in calcium homeostasis in muscle (PubMed:23362265, PubMed:9575189). Required for muscle-based, non-shivering thermogenesis (By similarity).
