My work is focused on cAMP as small signaling molecule that acts as a secondary messenger in animal cells and it is known to be involved in regulation of many important biological processes including primary metabolism, cell cycle, response to stress and hormonal homeostasis. Despite the fact that cAMP-dependent signaling cascades are well understood in animals, little is known about its potential function in plants. Although the presence of cAMP was recently confirmed in plant cells its protein interactors, with the exception of the family of the CNGC ion channels, are still nonidentified.

  In order to identify potential cAMP – protein interactions in plants, we decided to apply a range of new approaches, initially developed for mode of action research in the pharmacology field. Specifically, we adapted Drug Affinity Responsive Target Stability (DARTS) and Thermal Proteome Profiling (TPP) assays to plant lysates. Moreover, to complement DARTS and TPP, we also performed classical affinity purification using cAMP agarose beads. Starting with native lysates prepared from Arabidopsis cell cultures and using state of the art proteomic approach, we identified several proteins as candidates for cAMP interactors. At present, biophysical studies are performed to determine the binding affinity of these proteins to cAMP as a further validation of their role as cAMP binding proteins.

  With our studies we hope to unravel the mystery of cAMP signaling in plants.
