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.

Specific activation of cdc25 tyrosine phosphatases by B-type cyclins: evidence for multiple roles of mitotic cyclins.

Galaktionov K, Beach D

Two previously unidentified human cdc25 genes have been isolated, cdc25A and cdc25B. Both genes rescue a cdc25ts mutant of fission yeast. Microinjection of anti-cdc25A antibodies into HeLa cells causes their arrest in mitosis. cdc25A and cdc25B display endogenous tyrosine phosphatase activity that is stimulated several-fold, in the absence of cdc2, by stoichiometric addition of either cyclin B1 or B2 but ...

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.
