HOMOLOGY

FAMILY

CATEGORY

signaling

SUBCELLULAR LOCALIZATION	plasma membrane
	intracellular
	intracellular,cytoplasm
	intracellular,nuclear envelope

basic FUNCTION	playing a role in the release of ATP from human erythrocytes
	in stellate ganglion neurons, GNB2 and GNB4 normally maintain the coupling of Ca(2+) channels with the receptors, with the latter subtype responsible for maintaining the integrity of both pathways
	is required for starvation-induced NFKB1 activation and constitutive NFKB1 activity

a component

INTERACTION

DNA

RNA

small molecule

protein	interacting with ATXN10 (coexpression of ataxin 10 and GNB2 potently activated the Ras-MAP kinase-Elk-1 cascade, a mechanism for inducing neuritogenesis)
	KCNJ6 is capable of interacting with GNB1, GNB2, GNB3 and not GNB4 or GNB5
	GNGT1, GNG2, GNB1, GNB2, GNB3, interacts with MTOR and promotes its activation
