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.

SKP2 associates with p130 and accelerates p130 ubiquitylation and degradation in human cells.

Bhattacharya S, Garriga J, Calbo J, Yong T, Haines DS, Grana X

p130 is a member of the retinoblastoma family of pocket proteins, which includes pRB and p107. Unlike pRB and p107, p130 protein levels decrease dramatically following its hyperphosphorylation starting in the mid-G1 phase of the cell cycle. However, the mechanism leading to p130 downregulation is unknown. We have found that the proteasome inhibitor, lactacystin, inhibited p130 downregulation in T98G cells ... [more]

Biochemical Activity

An interaction is inferred from the biochemical effect of one protein upon another, for example, GTP-GDP exchange activity or phosphorylation of a substrate by a kinase. The bait protein executes the activity on the substrate hit protein. A Modification value is recorded for interactions of this type with the possible values Phosphorylation, Ubiquitination, Sumoylation, Dephosphorylation, Methylation, Prenylation, Acetylation, Deubiquitination, Proteolytic Processing, Glucosylation, Nedd(Rub1)ylation, Deacetylation, No Modification, Demethylation.
