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.

Sp4 is expressed in retinal neurons, activates transcription of photoreceptor-specific genes, and synergizes with Crx.
To investigate the molecular mechanisms of photoreceptor-specific gene transcription, we examined the role of the neuronal-enriched Sp4 nuclear protein in transcription from the rod-specific beta-PDE and rod opsin gene promoters and compared it to the ubiquitous members of the Sp family, Sp1 and Sp3. Sp4 activates both the rod opsin and beta-PDE promoters, whereas Sp1 activates only the rod opsin ... [more]
