Protein

Guanine nucleotide-binding protein G(I)/G(S)/G(T) subunit beta-2

Gene
Gnb2
Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 4 out of 5 - Experimental evidence at protein leveli

Functioni

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.
