Class B/2 (Secretin family receptors)

This family is known as Family B (secretin-receptor family, family 2) G-protein-coupled receptors. Family B GPCRs include secretin, calcitonin, parathyroid hormone/parathyroid hormone-related peptides and vasoactive intestinal peptide receptors; all of which activate adenylyl cyclase and the phosphatidyl-inositol-calcium pathway (Harmar AJ, 2001).

本家族被称为B家族（分泌素受体家族，家族2）G蛋白偶联受体。B家族G蛋白偶联受体包括分泌素、降钙素、甲状旁腺激素/甲状旁腺激素相关肽和血管活性肠肽受体；所有这些受体均能激活腺苷酸环化酶和磷脂酰肌醇钙途径（Harmar AJ，2001）。
