Purity ~80% (SDS-PAGE). Heterotrimeric G proteins, which consist of alpha, beta, and gamma subunits, function as signal transducers for the 7-transmembrane-helix G protein-coupled receptors. GNG13 is a gamma subunit that is expressed in taste, retinal, and neuronal tissues and plays a key role in taste transduction Source: Recombinant protein corresponding to aa1-64 from human GNG13, fused to His-tag at N-terminus, expressed in E.coli. Molecular Weight: ~10kD (87aa), confirmed by MALDI-TOF Applications: Suitable for use in SDS-PAGE.
