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.

MTA1 interacts with MAT1, a cyclin-dependent kinase-activating kinase complex ring finger factor, and regulates estrogen receptor transactivation functions.

The transcriptional activity of estrogen receptor-alpha is controlled by coregulators. MTA1 (metastasis-associated protein 1) represses estrogen receptor-alpha-driven transcription by recruiting histone deacetylases (HDACs) to the estrogen response element containing target gene chromatin in breast cancer cells. Using a yeast two-hybrid screen with the MTA1 C-terminal domain as bait, we identified MAT1 (menage a trois 1) as an MTA1-binding protein. MAT1 ... [more]

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.
