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.

Amyloid precursor proteins anchor CPEB to membranes and promote polyadenylation-induced translation.

Cao Q, Huang YS, Kan MC, Richter JD

The cytoplasmic polyadenylation element (CPE) binding factor, CPEB, is a sequence-specific RNA binding protein that controls polyadenylation-induced translation in germ cells and at postsynaptic sites of neurons. A yeast two-hybrid screen with a mouse brain cDNA library identified the transmembrane amyloid precursor-like protein 1 (APLP1) as a CPEB-interacting factor. CPEB binds the small intracellular domain (ICD) of APLP1 and the ... [more]
