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.

MAP kinase phosphorylation-dependent activation of Elk-1 leads to activation of the co-activator p300.

Li QJ, Yang SH, Maeda Y, Sladek FM, Sharrocks AD, Martins-Green M

CBP/p300 recruitment to enhancer-bound complexes is a key determinant in promoter activation by many transcription factors. We present a novel mechanism of activating such complexes and show that pre-assembled Elk-1-p300 complexes become activated following Elk-1 phosphorylation by changes in Elk-1-p300 interactions rather than recruitment. It is known that Elk-1 binds to promoter in the absence of stimuli. However, it is ... [more]

Phenotypic Enhancement

A genetic interaction is inferred when mutation or overexpression of one gene results in enhancement of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.
