What is the official name of the GHRHR gene?
The official name of this gene is “growth hormone releasing hormone receptor.”
GHRHR is the gene's official symbol. The GHRHR gene is also known by other names, listed below.

What is the normal function of the GHRHR gene?
The GHRHR gene provides instructions for making the growth hormone releasing hormone receptor. This receptor is active (expressed) on the growth-stimulating somatotropic cells in the pituitary gland. This gland is is located at the base of the brain and produces many hormones, including growth hormone. Growth hormone is necessary for the normal growth of the body's bones and tissues. The GHRHR receptor attaches (binds) to a molecule called growth hormone releasing hormone. This binding, along with the actions of other molecules, triggers the production of growth hormone and its release from the pituitary gland.
Does the GHRHR gene share characteristics with other genes?
The GHRHR gene belongs to a family of genes called GPCR (G protein-coupled receptors).
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.
