In Arabidopsis thaliana, 20 genes (MPKs) encode putative plant MAPKs, which can be grouped into four or five classes according to sequence similarity. All plant MAPKs are classified into the plant extracellular-regulated kinase/ERK (PERK) subfamily.
Immunogen
synthetic peptide corresponding to the C-terminus of Arabidopsis thaliana MPK6 (amino acids 384-395). This sequence is specific to AtMPK6 (not found in the other 20 known AtMPK isoforms). It shares limited homology (40-50% identity) to the AtMPK3 and AtMPK4 isoforms, and is highly conserved in the Nicotiana tabacum ortholog SIPK.
Application
Anti-AtMPK6 antibody produced in rabbit has been used in immunoblotting.[1]
Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below. Western Blotting (1 paper)
Biochem/physiol Actions
Mitogen-activated protein kinase (MAPK) cascades are among the most conserved signal transduction pathways in eukaryotes. MAPKs regulate a variety of cellular activities ranging from gene expression, cell proliferation, motility, metabolism and apoptosis. In Arabidopsis thaliana putative functions have been assigned to AtMPK3, AtMPK4 and AtMPK6 and all three MAPKs have been linked to diverse stress responses, including oxidative stress signaling, pathogen defense, drought, high salt, cold and touch.

S-acylation is a common post-translational modification of membrane protein cysteine residues with many regulatory roles. S-acylation adjacent to transmembrane domains has been described in the literature as affecting diverse protein properties including turnover, trafficking and microdomain partitioning. However, all of
A Suite of Receptor-Like Kinases and a Putative Mechano-Sensitive Channel Are Involved in Autoimmunity and Plasma Membrane-Based Defenses in Arabidopsis
Receptor-like kinases (RLKs) are the largest family of proteins in plants and are responsible for perceiving the vast majority of extracellular stimuli. Thus, RLKs function in diverse processes, including sensing pathogen attacks, regulating symbiotic interactions, transducing hormone and peptide signals
Activation and function of the MAPKs and their substrates, the MAPK-activated protein kinases
In the present work, we provide an account of structured illumination microscopy (SIM) imaging of fixed and immunolabeled plant probes. We take advantage of SIM, to superresolve intracellular structures at a considerable z-range and circumvent its low temporal resolution capacity
