ABSTRACT:
A Corticotropin Releasing Factor-binding protein (CRF-BP) is isolated and purified sufficient to provide AA sequence data from which the DNA is obtained, which is then used to produce the protein recombinantly. The CRF-BP is useful for modulating the biological activity of CRF, such as reducing the high ACTH levels in mammals caused by excess CRF. The CRF-BP or fragments thereof and/or antibodies to the proteins may be employed in diagnostic assays to determine the levels of CRF, CRF-BP and the ratio of CRF/CRF-BP in a vascular fluid sample. The DNA or subsequence thereof can be used as probes for genetic material in certain assays. The anti-CRF-BP antibodies are also useful to purify the CRF-BP protein and to modulate the biological effect of CRF-BPs proteins.
