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.

SR protein kinases promote splicing of nonconsensus introns.

Lipp JJ, Marvin MC, Shokat KM, Guthrie C

Phosphorylation of the spliceosome is essential for RNA splicing, yet how and to what extent kinase signaling affects splicing have not been defined on a genome-wide basis. Using a chemical genetic approach, we show in Schizosaccharomyces pombe that the SR protein kinase Dsk1 is required for efficient splicing of introns with suboptimal splice sites. Systematic substrate mapping in fission yeast ... [more]

Additional Notes

  • We labeled HeLa extracts with N6-phenethyl-ATP-gammaS in the presence of either recombinant WT or analog-sensitive Srpk2. We then purified thiophosphorylated peptides and identified Srpk2 substrates as well as their phosphorylation sites by MS

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.

FRET

An interaction is inferred when close proximity of interaction partners is detected by fluorescence resonance energy transfer between pairs of fluorophore-labeled molecules, such as occurs between CFP (donor) and YFP (acceptor) fusion proteins.
