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.

The carboxy-terminal, M3 motifs of PACT and TRBP have opposite effects on PKR activity.

Gupta V, Huang X, Patel RC

PKR is an interferon(IFN)-induced, serine-threonine protein kinase, which plays a crucial role in IFN's antiviral and antiproliferative actions. The three known activators of PKR are dsRNA, heparin, and PACT. PACT activates PKR by direct protein-protein interaction in response to cellular stress. The human TAR (trans-activating region)-binding protein (TRBP), which is very homologous to PACT, also interacts with PKR, leading to ... [more]

Co-crystal Structure
Co-crystal Structure

Interaction directly demonstrated at the atomic level by X-ray crystallography. Also used for NMR or Electron Microscopy (EM) structures. If there is no obvious bait-hit directionality to the interaction involving 3 or more proteins, then the co-crystallized proteins should be listed as a complex.

Phenotypic Enhancement
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.
