DESCRIPTION

Also known as GBB1_HUMAN, GNB1. Guanine nucleotide-binding proteins (G proteins) are involved as a modulator or transducer in various transmembrane signaling systems. The beta and gamma chains are required for the GTPase activity, for replacement of GDP by GTP, and for G protein-effector interaction. G proteins are composed of 3 units, alpha, beta and gamma (By similarity). The heterodimer formed by GNB1 and GNG2 interacts with ARHGEF5 (PubMed:19713215). The heterodimer formed by GNB1 and GNG2 interacts with GRK2 (By similarity). Forms a complex with GNAO1 and GNG3 (PubMed:34685729). Interacts with ARHGEF18 and RASD2 (PubMed:14512443, PubMed:19255495).
