Purity ~85% (SDS-PAGE). GNG12 is also known as Guanine nucleotide-binding protein G(I)/G(S)/G(O)subunit gamma-12. 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. Source: Recombinant protein corresponding to aa1-69 from human GNG12, expressed in E.coli. Molecular Weight: ~10.1kD (92aa) Applications: Suitable for use in SDS-PAGE.
