Immuno-Grade Corticotropin-Releasing Factor Receptor 1 Antibodies
The CRF1 receptor is widely expressed in the central nervous system with high levels of expression in cortex, cerebellum, hippocampus, basolateral amygdala, bed nucleus of the stria terminalis, olfactory bulb and anterior pituitary. In the periphery, CRF1 receptor is expressed at low levels in the skin, ovary, testis and adrenal gland. CRF, urocortin 1 (UCN1) and urotensin I all bind with high affinity to the mammalian CRF1 receptor and activate the cyclic AMP signaling pathway. In contrast, UCN2 and UCN3 do not bind to or activate CRF1 receptors. Therefore, CRF and urocortin 1 can be classified as the endogenous ligands for mammalian CRF1 receptors.
