G-protein coupled receptor kinase 3 (GRK3) mediates desensitization of alpha(2)-adrenergic (alpha(2)-AR) and CRF1 receptors. CRF1 receptors, alpha(2)-AR and GRK3, are localized to the primary source of noradrenergic inputs to higher brain centers critical in both the response to stress and the development of depression, namely, locus coeruleus (LC). This study utilizing CATH.a cells (derived from the LC), demonstrates for the first time, that the stress hormone, CRF selectively up-regulates GRK3 expression via an ERK1/2-mediated mechanism accompanied by the activation of Sp-1 and Ap-2 transcription factors. This observation has important implications for the regulation of stress signaling in the brain. (C) 2007 Federation of European Biochemical Societies. Published by Elsevier B.V. All rights reserved.
