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 DARPP-32, a dopamine- and cAMP-regulated phosphoprotein, by casein kinase II.

Girault JA, Hemmings HC, Williams KR, Nairn AC, Greengard P

DARPP-32 (dopamine- and cAMP-regulated phosphorprotein, Mr = 32,000 as determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis) is an inhibitor of protein phosphatase-1 and is enriched in dopaminoceptive neurons possessing the D1 dopamine receptor. Purified bovine DARPP-32 was phosphorylated in vitro by casein kinase II to a stoichiometry greater than 2 mol of phosphate/mol of protein whereas two structurally and functionally ... [more]
