Recombinant Human S100A1 Protein (Gst Tag)

Small calcium binding protein that plays important roles in several biological processes such as Ca2+ homeostasis, chondrocyte biology and cardiomyocyte regulation (PubMed:12804600) . In response to an increase in intracellular Ca2+ levels, binds calcium which triggers conformational changes (PubMed:23351007) . These changes allow interactions with specific target proteins and modulate their activity (PubMed:22399290) . Regulates a network in cardiomyocytes controlling sarcoplasmic reticulum Ca2+ cycling and mitochondrial function through interaction with the ryanodine receptors RYR1 and RYR2, sarcoplasmic reticulum Ca2+-ATPase/ATP2A2 and mitochondrial F1-ATPase (PubMed:12804600) . Facilitates diastolic Ca2+ dissociation and myofilament mechanics in order to improve relaxation during diastole.

Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80°C. Reconstituted protein solution can be stored at 4-8°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
