Plants contain hundreds of protein kinases that are believed to provide cellular signal transduction services, but the identities of the proteins they are targeting are largely unknown. Using an Arabidopsis MAPK (mitogen-activated protein kinase) (MPK6) as a model, Sörensson et al. describe in this issue of the Biochemical Journal how arrayed combinatorial peptide scanning offers an efficient route to discovery of new potential kinase substrates.
