Arabidopsis MAP kinase phosphatase 1 (AtMKP1) is a member of the mitogen-activated protein kinase (MPK) phosphatase family, which negatively regulates AtMPKs. We have previously shown that AtMKP1 is regulated by calmodulin (CaM). Here, we examined the phosphorylation of AtMKP1 by its substrate AtMPK6. Intriguingly, AtMKP1 was phosphorylated by AtMPK6, one of AtMKP1 substrates. Four phosphorylation sites were identified by phosphoamino ... [more]

Biochemical Activity

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.
