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.

Mdm2 directs the ubiquitination of beta-arrestin-sequestered cAMP phosphodiesterase-4D5.

Li X, Baillie GS, Houslay MD

Beta-arrestin plays a key role in regulating beta2-adrenoreceptor signaling by interdicting activation of adenylyl cyclase and selectively sequestering cAMP phosphodiesterase-4D5 (PDE4D5) for delivery of an active cAMP degrading system to the site of cAMP synthesis. Here we show that the beta-agonist, isoprenaline, triggers the rapid and transient ubiquitination of PDE4D5 in primary cardiomyocytes, mouse embryo fibroblasts, and HEK293B2 cells constitutively ...
