human alpha-cgrp

Rat CGRP-(8-37) (VTHRLAGLLSRSGGVVKDNFVPTNVGSEAF) is a highly selective CGRP receptor antagonist

Tyr-α-CGRP is an N-terminal extended tyrosinated analogue of α-calcitonin gene-related peptide . It binds to amylin receptors AMY1 and AMY3 in COS-7 cells expressing the human receptors (IC50s = 141 and 1.86 nM, respectively). Tyr-α-CGRP also binds to and stimulates cAMP accumulation in rat L6 myocytes (IC50 = 4 nM; EC50 = 12 nM). It also binds to rat brain and spleen membrane preparations (IC50s = 0.2 and 0.5 nM, respectively), induces positive chronotropic and inotropic effects in isolated right and left guinea pig atria (EC50s = 282 and 74 nM, respectively), and inhibits the twitch response in rat vas deferens (EC50 = 1.9 nM).

Endogenous calcitonin gene-related peptide receptor (CGRP) agonist.
