Receptor-Mediated Adenylyl Cyclase Activation Through XLαs, the Extra-Large Variant of the Stimulatory G Protein α-Subunit (2002, background): “Such cell lines will also be useful for investigating whether both signaling proteins interact selectively with different -subunits, and/or with proteins that modulate their activity, such as RGS-PX1, a recently reported GTP phosphohydrolase activating protein that attenuates Gs-mediated signaling (”
Systemic effects of chronic obstructive pulmonary disease (2003, background): “Gas is involved in the intracellular signal transduction pathway linked to CD11b expression [24] and also in the control of intracellular vesicular trafficking [26], the latter being relevant for correct activation of reduced nicotinamide adenine dinucleotide phosphate oxidase, the enzyme eventually”
