RGS21, a regulator of taste and mucociliary clearance?

Conclusions Rgs21 is expressed in sinonsal mucosa, is amenable to purification as a recombinant protein, and can bind to Gαi/o/q subunits. Furthermore, RGS21 can accelerate the hydrolysis rate of GTP on Gαi subunits. This provides evidence that RGS21 may be a negative regulator of bitterant responses. Future studies will be needed to determine the physiological role of this protein in mucociliary clearance. Level of EvidenceNA Laryngoscope, 2013
