The function of the CELA2A protein as elastase goes beyond its traditional role as it not only enhances insulin signaling but also appears to play a potential physiological role in cellular glucose metabolism. This multifaceted protein circulates in the plasma and exerts regulatory effects by reducing platelet overactivation. CELA2A Protein, Human (His) is the recombinant human-derived CELA2A protein, expressed by E. coli , with N-6*His labeled tag.
