Corticotropin-Releasing Factor Type-1 Receptor (CRF1)
- Target
- CRF1
- Molecular classification
- G protein-coupled receptor, GPCR, Class B GPCR, Receptor
01
Overview
The corticotropin-releasing factor type‑I receptor (CRF1) is a class B GPCR essential for mediating neuroendocrine responses to stress through activation by its ligands—primarily corticotropin-releasing hormone—and subsequent stimulation of intracellular cAMP signaling pathways. It plays a pivotal role both developmentally and physiologically within systems governing homeostasis and behavioral adaptation under stressful conditions. Its dysfunction has broad implications for mental health disorders related to abnormal HPA axis activity.
