CRF (human, rat)
Cat. No. CR-020
Structure:
H-Ser-Glu-Glu-Pro-Pro-Ile-Ser-Leu-Asp-Leu-Thr-Phe-His-Leu-Leu-Arg-Glu-Val-Leu-Glu-Met-Ala-Arg-Ala-Glu-Gln-Leu-Ala-Gln-Gln-Ala-His-Ser-Asn-Arg-Lys-Leu-Met-Glu-Ile-Ile-NH2
Other Names:
Corticotropin releasing factor (human, rat), Corticotropin releasing hormone, CRH
Activity:
Endogenous CRF receptor agonist
CRF (human, rat) is an endogenous peptide derived from a 196-amino acid preprohormone which acts as an agonist for CRF receptors, with Ki values of 11, 44 and 38 nM for hCRF1, rCRF2a and mCRF2b respectively. CRF (human, rat) is a major regulator of the hypothalamic pituitary adrenal axis response and is a stress-related neuropeptide whose dysregulation has been associated with depression. Increased CRF (human, rat) production is also associated with Alzheimer's disease.
