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:21697544, PubMed:22961106, PubMed:26816378, PubMed:31449798). Also inhibits the activity of ATP2A3/SERCA3 (PubMed:27923914). Modulates calcium re-uptake during muscle relaxation and plays an important role in calcium homeostasis in muscle (PubMed:21697544, PubMed:26816378). Required for muscle-based, non-shivering thermogenesis (PubMed:22961106).
