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 hTERT and hTERC telomerase gene promoters are activated by the second exon of the adenoviral protein, E1A, identifying the transcriptional corepressor CtBP as a potential repressor of both genes.
Telomerase plays a role in the unlimited replicative capacity of the majority of cancer cells and provides a potential anticancer target. The regulation of telomerase is complex but transcriptional control of its two essential components, hTERC (RNA component) and hTERT (reverse transcriptase component), is of major importance. To investigate this further, we have used the adenoviral protein, E1A, as a ... [more]
