Interaction of activator of G-protein signaling 3 (AGS3) with LKB1, a serine/threonine kinase involved in cell polarity and cell cycle progression: phosphorylation of the G-protein regulatory (GPR) motif as a regulatory mechanism for the interaction of GPR motifs with Gi alpha.

Blumer JB, Bernard ML, Peterson YK, Nezu J, Chung P, Dunican DJ, Knoblich JA, Lanier SM

Activator of G-protein signaling 3 (AGS3) has a modular domain structure consisting of seven tetratricopeptide repeats (TPRs) and four G-protein regulatory (GPR) motifs. Each GPR motif binds to the alpha subunit of Gi/Go (Gialpha > Goalpha) stabilizing the GDP-bound conformation of Galpha and apparently competing with Gbetagamma for GalphaGDP binding. As an initial approach to identify regulatory mechanisms for AGS3-G-protein ... [more]

Affinity Capture-Western
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.
