Interactors of the plant natriuretic peptide present in Arabidopsis thaliana, termed AtPNP-A, were affinity-based isolated from A. thaliana (Col-0) leaf mesophyll cell protoplasts by incubating the protoplasts with biologically active biotinylated peptide corresponding to amino acid sequence of the active site of AtPNP-A (pAtPNP-A), either in the presence or absence of a cross-linking agent, 3,3′-dithiobis(sulfosuccinimidyl propionate) (DTSSP), or with equimolar amount of biotin with DTSSP (negative control). Upon biotin/streptavidin-based isolation of proteins bound to the pAtPNP-A or biotin, the proteins were separated by sodium dodecyl sulphate – polyacrylamide gel electrophoresis (SDS-PAGE), digested with trypsin and subjected to identification with liquid chromatography tandem mass spectrometry (LC-MS/MS). Label-free quantification of identified proteins allowed identification of binding partners of AtPNP-A, paving the way for pinpointing novel signal transduction pathways AtPNP-A is involved in. The raw and processed LC-MS/MS data reported in this article have been deposited to the ProteomeXchange Consortium with the dataset identifier PXD017925.
