Figure 2From: Biological functions of hCG and hCG-related moleculesActivation of hCG/LH receptor, G protein and cAMP, protein kinase expression, and production of hCG/LH receptor binding protein (LHRBP). Synthesis of LHRBP activates exo- and endonucleases which destroy receptor mRNA, limiting expression and down regulating the receptor.Back to article page
