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 Pirh2 by calmodulin-dependent kinase II impairs its ability to ubiquitinate p53.

Duan S, Yao Z, Hou D, Wu Z, Zhu WG, Wu M

Although the recently identified Pirh2 protein is known as a p53-induced ubiquitin-protein E3 ligase, which negatively regulates p53, the detailed mechanism underlying the regulation of Pirh2 remains largely unknown. Here, we demonstrate that while Pirh2 is mostly detected in the phosphorylated form in normal tissues, it is predominantly present in the unphosphorylated form in majority of tumor cell lines and ...
