Identification of constitutively active AtMPK6 mutants using a functional screen in Saccharomyces cerevisiae

Methods Mol Biol. 2014:1171:67-77. doi: 10.1007/978-1-4939-0922-3_6.

Abstract

MAPK (Mitogen-Activated Protein Kinases) mutants which are active independently of phosphorylation by upstream MAPK Kinases (MAPKKs) help to clarify signal transduction processes through MAPK modules and provide a useful tool to understand MAPK roles in the cell. The identification of such mutations is tricky. In this chapter, we provide a detailed protocol for their screening, taking advantage of a functional expression assay in yeast.
