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.

Physical and functional interactions of Galphaq with Rho and its exchange factors.

Sagi SA, Seasholtz TM, Kobiashvili M, Wilson BA, Toksoz D, Brown JH

Recent reports have shown that several heterotrimeric protein-coupled receptors that signal through Galpha(q) can induce Rho-dependent responses, but the pathways that mediate the interaction between Galpha(q) and Rho have not yet been identified. In this report we present evidence that Galpha(q) expressed in COS-7 cells coprecipitates with the Rho guanine nucleotide exchange factor (GEF) Lbc. Furthermore, Galpha(q) expression enhances Rho-dependent ... [more]
