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.

Compensatory contributions of HEXIM1 and HEXIM2 in maintaining the balance of active and inactive positive transcription elongation factor b complexes for control of transcription.
Human positive transcriptional elongation factor b (P-TEFb), consisting of a cyclin-dependent kinase 9-cyclin T heterodimer, stimulates general and disease-specific transcriptional elongation by phosphorylating RNA polymerase II. The HEXIM1 protein, aided by the 7SK snRNA, sequesters P-TEFb into an inactive 7SK.HEXIM1.P-TEFb small nuclear ribonucleic acid particle for inhibition of transcription and, consequently, cell proliferation. Here we show that, like HEXIM1, a ... [more]
