Corticotropin-releasing hormone (CRH) and CRH-relate urocortin (UCN) peptides exert a wide range of functions, from setting in motion the stress-responding hypothalamus-pituitary-adrenal (HPA) axis to various actions in central nervous system (CNS) and the periphery. The signaling initiated by these peptides engages two receptor types belonging to the secretin family of G-protein coupled receptors (GPCR). CRH is a main component of the HPA axis; released by the hypothalamus in response to stres

Object TypePathway ObjectPathway Object Description
PathwayG protein mediated signaling pathway via Galphas familybased on sequence similarity, the Galpha genes have been grouped into four classes. Effectors of activated Galphas are adenylyl cyclases that catalyze the formation of cAMP
Small MoleculecAMPcAMP binding to the PKA complex leads to dissociation of the catalytic subunits
Pathwayprotein kinase A (PKA) signaling pathwayProtein kinase A (PKA) signaling is a widely used intracellular pathway and the major route for channeling the second messenger cAMP signal
Pathwaymelanocortin system pathwayThe melanocortin peptides derived from the processing of POMC gene product, bind to specifc G-protein coupled receptors to elicit a range of responses. Activation of HPA axis leads to expression of POMC gene
