RGS5, an adept signal transduction modulator, enhances G protein alpha subunit GTPase activity, promoting their transition to the inactive GDP-bound state. Interacting with G (i) -alpha and G (o) -alpha, it selectively excludes G (s) -alpha, highlighting its precise role in regulating specific G protein subunits and fine-tuning cellular signaling pathways. RGS5 Protein, Human (His) is the recombinant human-derived RGS5 protein, expressed by E. coli , with N-6*His labeled tag.
