Co-localization

Interaction inferred from two proteins that co-localize in the cell by indirect immunofluorescence only when in addition, if one gene is deleted, the other protein becomes mis-localized. Also includes co-dependent association of proteins with promoter DNA in chromatin immunoprecipitation experiments.

Cyclin-dependent kinase-9 is a component of the p300/GATA4 complex required for phenylephrine-induced hypertrophy in cardiomyocytes.

A zinc finger protein GATA4 is one of the hypertrophy-responsive transcription factors and forms a complex with an intrinsic histone acetyltransferase, p300. Disruption of this complex results in the inhibition of cardiomyocyte hypertrophy and heart failure in vivo. By tandem affinity purification and mass spectrometric analyses, we identified cyclin-dependent kinase-9 (Cdk9) as a novel GATA4-binding partner. Cdk9 also formed a ... [more]

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.
