MAP Kinase Peptides
A specific sequence for MAP kinases
APRTPGGRR is specific for MAP kinases: p44MAPK [extracellular signal-regulated kinase 1 (ERK1)] and p42MAPK (ERK2).
It contains the consensus sequence Pro-X-(Ser/Thr)-Pro that is recognized by MAP kinase.
APRTPGGRR is the most efficient substrate for phosphorylation reaction by ERK and is phosphorylated by kinases on threonine 97 and can also be phosphorylated by MAPK p38.
