Sermorelin is a synthetic 29-amino acid peptide corresponding to the first 29 residues of endogenous growth hormone-releasing hormone (GHRH 1-29). It binds to GHRH receptors (GHRHR) on somatotroph cells, activating Gs-coupled adenylyl cyclase and downstream cAMP/PKA/CREB signaling cascades. Sermorelin is studied in vitro for GHRHR binding kinetics, receptor desensitization assays, and cAMP-dependent transcriptional activation in cell-based models. For in vitro research use only. Not for human or veterinary use.
