Calcitonin R protein, a receptor for calcitonin, utilizes G proteins to activate adenylyl cyclase. Despite being sensitive to cholera toxin, it exhibits limited coupling to G proteins, leading to the inability to effectively activate adenylyl cyclase. Notably, following ligand binding, Calcitonin R does not undergo the conventional process of receptor internalization. Calcitonin R Protein, Human (130a.a, HEK293, Fc) is the recombinant human-derived Calcitonin R, expressed by HEK293, with N-hFc labeled tag. The total length of Calcitonin R Protein, Human (130a.a, HEK293, Fc) is 130 a.a..
