Affinity Capture-Western

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner identified by Western blot with a specific polyclonal antibody or second epitope tag. This category is also used if an interacting protein is visualized directly by dye stain or radioactivity. Note that this differs from any co-purification experiment involving affinity capture in that the co-purification experiment involves at least one extra purification step to get rid of potential contaminating proteins.

Activated G alpha q inhibits p110 alpha phosphatidylinositol 3-kinase and Akt.

Ballou LM, Lin HY, Fan G, Jiang YP, Lin RZ

Some Gq-coupled receptors have been shown to antagonize growth factor activation of phosphatidylinositol 3-kinase (PI3K) and its downstream effector, Akt. We used a constitutively active Galphaq(Q209L) mutant to explore the effects of Galphaq activation on signaling through the PI3K/Akt pathway. Transient expression of Galphaq(Q209L) in Rat-1 fibroblasts inhibited Akt activation induced by platelet-derived growth factor or insulin treatment. Expression of ... [more]
