HOMOLOGY

Homologene

FAMILY	G protein coupled receptor superfamily
	secretin family, coupling with Gs alpha protein and activating adenylate cyclase

CATEGORY

signaling hormone , receptor

SUBCELLULAR LOCALIZATION	plasma membrane
text	localizes to the surface of somatotroph cells and binds GHRH

basic FUNCTION	stimulating somatotroph cell growth, growth hormone gene transcription and growth hormone secretion
	can form multimers, which may be important to its signaling properties
