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.

The substrate specificity and structure of mitogen-activated protein (MAP) kinase-activated protein kinase-2.

Stokoe D, Caudwell B, Cohen PT, Cohen P

The substrate specificity of mitogen-activated protein (MAP) kinase-activated protein kinase-2 (MAPKAP kinase-2) was investigated by using synthetic peptides related to the N-terminus of glycogen synthase. The minimum sequence required for efficient phosphorylation was found to be Xaa-Xaa-Hyd-Xaa-Arg-Xaa-Xaa-Ser-Xaa-Xaa, where Hyd is a bulky hydrophobic residue (Phe > Leu > Val > Ala), and the peptide Lys-Lys-Phe-Asn-Arg-Thr-Leu-Ser-Val-Ala was phosphorylated with a Km ...
