Recombinant Human Calsequestrin/CASQ1 Protein (RPES4009)

Human Calsequestrin/CASQ1 Recombinant Protein (RPES4009) is a highly pure recombinant protein developed by Assay Genie for use in a range of applications Protein function: Calsequestrin is a high-capacity, moderate affinity, calcium- binding protein and thus acts as an internal calcium store in muscle (PubMed:28895244). Calcium ions are bound by clusters of acidic residues at the protein surface, often at the interface between subunits. Can bind around 80 Ca(2+) ions (PubMed:28895244). Regulates the release of lumenal Ca(2+) via the calcium release channel RYR1, this plays an important role in triggering muscle contraction. Negatively regulates store-operated Ca(2+) entry (SOCE) activity (PubMed:27185316). [The UniProt Consortium]
