Overview

« Hide More detailed introduction

Corticotropin-releasing factor (CRF, nomenclature as agreed by the NC-IUPHAR subcommittee on Corticotropin-releasing Factor Receptors [7]) receptors are activated by the endogenous peptides corticotrophin-releasing hormone (CRH, P06850), a 41 amino-acid peptide, urocortin 1 (UCN, P55089), 40 amino-acids, urocortin 2 (UCN2, Q96RP3), 38 amino-acids and urocortin 3 (UCN3, Q969E3), 38 amino-acids. CRF1 and CRF2 receptors are activated non-selectively by corticotrophin-releasing hormone (CRH, P06850) and urocortin 1 (UCN, P55089). Binding to CRF receptors can be conducted using [125I]Tyr0-CRF or [125I]Tyr0-sauvagine with Kd values of 0.1-0.4 nM. CRF1 and CRF2 receptors are non-selectively antagonized by α-helical CRF, D-Phe-CRF-(12-41) and astressin.
