GNGT2 GBGT2_CANFA Guanine nucleotide-binding protein G(I)/G(S)/G(O) subunit gamma-T2 Tgamma c 69 MAQELSEKELLKMEVEQLKKEVKNPRALISKTGKEIKDYVEAEAGNDPLLKGIPEDKNPFKEKGGCMIS 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 gamma-C
