Co-fractionation

Interaction inferred from the presence of two or more protein subunits in a partially purified protein preparation. If co-fractionation is demonstrated between 3 or more proteins, then add them as a complex.

Purification of P-TEFb, a transcription factor required for the transition into productive elongation.

Marshall NF, Price DH

Production of full-length runoff transcripts in vitro and functional mRNA in vivo is sensitive to the drug 5,6-dichloro-1-beta-D-ribofuranosylbenzimidazole (DRB). We previously proposed the existence of an activity, P-TEF (positive transcription elongation factor) that functions in a DRB-sensitive manner to allow RNA polymerase II elongation complexes to efficiently synthesize long transcripts (Marshall, N. F. and Price, D. H. (1992) Mol. Cell. ... [more]

Affinity Capture-MS

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 is identified by mass spectrometric methods.

CYCT CDK9
Affinity Capture-Western
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.
