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.

Taf(II) 250 phosphorylates human transcription factor IIA on serine residues important for TBP binding and transcription activity.

Solow S, Salunek M, Ryan R, Lieberman PM

Transcription factor IIA (TFIIA) is a positive acting general factor that contacts the TATA-binding protein (TBP) and mediates an activator-induced conformational change in the transcription factor IID (TFIID) complex. Previously, we have found that phosphorylation of yeast TFIIA stimulates TFIIA.TBP.TATA complex formation and transcription activation in vivo. We now show that human TFIIA is phosphorylated in vivo on serine residues ... [more]
