Biochemical Activity (Phosphorylation)

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.

Phosphorylation of ataxin-3 by glycogen synthase kinase 3beta at serine 256 regulates the aggregation of ataxin-3.

Machado-Joseph disease (MJD) is a dominant neurodegenerative disorder caused by an expansion of the polyglutamine tract in MJD-1 gene product, ataxin-3. Recently, studies show that phosphorylation of polyglutamine disease proteins, such as huntingtin, ataxin-1 and DRPLA, plays an important role in regulating pathogenesis. However, the kinase that phosphorylates ataxin-3 remains unknown. Here we show that S256 site in ataxin-3 is ... [more]

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.
