D P Behan et al.
Molecular psychiatry, 1(4), 265-277 (1996-09-01)
The actions of CRF in the brain and in the periphery are mediated through multiple binding sites. There are three receptors, CRF1, CRF2 alpha and CRF2 beta, which encode 411, 415 and 431 amino acid proteins and transduce signals via
S C Heinrichs et al.
Proceedings of the National Academy of Sciences of the United States of America, 93(26), 15475-15480 (1996-12-24)
Elevation of the neuropeptide corticotropin-releasing factor (CRF) in the brain is associated with a reduction of food intake and body weight gain in normal and obese animals. A protein that binds CRF and the related peptide, urocortin, with high affinity
