Indeed, there are around 30 isoforms of RGS proteins that, when bound to Gα through their GAP domain, accelerate the hydrolysis rate to ≈30 times/sec.
Memang, ada sekitar 30 isoform protein RGS yang, ketika terikat ke Gα melalui domain GAP mereka, mempercepat laju hidrolisis menjadi ≈30 kali / detik.
