Gene: GNB1 (G protein subunit beta 1) Homo sapiens
Symbol: GNB1
Name: G protein subunit beta 1
Description: Exhibits GTPase activity and GTPase binding activity. Predicted to be involved in adenylate cyclase-activating dopamine receptor signaling pathway and cellular response to prostaglandin E stimulus. Localizes to the heterotrimeric G-protein complex. Implicated in autosomal dominant non-syndromic intellectual disability 42 and precursor lymphoblastic lymphoma/leukemia.
Type: protein-coding
RefSeq Status: REVIEWED
