Growth Hormone Releasing Hormone

Introduction

Growth hormone releasing hormone (GHRH) is a secretory neurohormone that causes growth hormone to be released from the pituitary gland. It is naturally produced in the arcuate nucleus of the hypothalamus. The hormone is produced as a 44 amino acid peptide hormone, and first appears in the hypothalamus between 18 and 29 weeks of gestation, corresponding to the initial production of growth hormone by the fetus [1]. Growth hormone is required for normal fetal and post fetal development, including bone growth and the regulation of protein production and the metabolism of lipids and carbohydrates [2].

GHRH Receptor

The GHRH receptor gene is expressed in the pituitary as a G-coupled receptor that binds GHRH, resulting in the release of growth hormone [3]. The figure below and to the left is the extracellular domain of the GHRH receptor.
