DESCRIPTION

Also known as GBB1_RAT, 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 (By similarity). The heterodimer formed by GNB1 and GNG2 interacts with GRK2 (By similarity). Interacts with ARHGEF18 and RASD2 (By similarity).
