Biochemical Activity (Dephosphorylation)

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.

Dephosphorylation of tau by protein phosphatase 5: impairment in Alzheimer's disease.

Liu F, Iqbal K, Grundke-Iqbal I, Rossie S, Gong CX

Protein phosphatase (PP) 5 is highly expressed in the mammalian brain, but few physiological substrates have yet been identified. Here, we investigated the kinetics of dephosphoryation of phospho-tau by PP5 and found that PP5 had a K(m) of 8-13 microm toward tau, which is similar to that of PP2A, the major known tau phosphatase. This K(m) value is within the ... [more]
