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 the BRCA1 C terminus (BRCT) repeat inhibitor of hTERT (BRIT1) protein coordinates TopBP1 protein recruitment and amplifies ataxia telangiectasia-mutated and Rad3-related (ATR) Signaling.
The ataxia telangiectasia-mutated and Rad3-related (ATR) kinase functions as a central node in the DNA damage response signaling network. The mechanisms by which ATR activity is amplified and/or maintained are not understood. Here we demonstrate that BRIT1/microcephalin (MCPH1), a human disease-related protein, is dispensable for the initiation but essential for the amplification of ATR signaling. BRIT1 interacts with and recruits ... [more]
