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 RNA-splicing factor PSF/p54 controls DNA-topoisomerase I activity by a direct interaction.
DNA-topoisomerase I has been implied in RNA splicing because it catalyzes RNA strand transfer and activates serine/arginine-rich RNA-splicing factors by phosphorylation. Here, we demonstrate a direct interaction between topoisomerase I and pyrimidine tract binding protein-associated splicing factor (PSF), a cofactor of RNA splicing, which forms heterodimers with its smaller homolog, the nuclear RNA-binding protein of 54 kDa (p54). Topoisomerase I, ... [more]
