ProteomicsPhosphorylation dynamics in a flg22-induced, G-protein dependent network reveals the RGS1 phosphatase
The Microbe Associated Molecular Pattern flg22 is recognized in a FLAGELLIN-SENSITVE 2-dependent manner in root tip cells. Here, we show a rapid and massive change in protein abundance and phosphorylation state of the Arabidopsis root cell proteome in wildtype and a mutant deficient in heterotrimer...

ProteomicsIdentification of the Kinase phosphorylation sites on AtGPA1 in presence of GTP
Phosphorylation of GPA1 has been shown to functionally important in vitro and in vivo. We previously identified18 LRR RLKs transphosphorylation of AtGPA1 via in vitro kinase assay using recombinant kinase domains and AtGPA1 (Bo et al., J Biol Chem 293(13): 4752-4766). Among them, we choose 12 kinase...

ProteomicsIdentification of the Kinase phosphorylation sites on AtGPA1 in presence of GDP
Phosphorylation of GPA1 has been shown to functionally important in vitro and in vivo. We previously identified18 LRR RLKs transphosphorylation of AtGPA1 via in vitro kinase assay using recombinant kinase domains and AtGPA1 (Bo et al., 2018, J. Biol. Chem 293(13): 4752-4766). Among them, we here cho...

ProteomicsLeaf protein extraction method
We evaluated several approaches for sample processing that are based on popular urea extraction, methanol/chloroform, and phenol methods. Additionally, we examined whether these methods were improved using FASP-based on filter digestion. We found that phenol-FASP and UA-FASP methods enabled the bes...

ProteomicsMouse Placenta Proteome and Phosphoproteome
TMT based quantification of protein abundance and phosphorylation state for developing mouse placenta. Timed-pregnant CD-1 mice were obtained from Charles Rivers Labs and dissected at e7.5 to extract the ectoplacental cones (EPCs) and at e9.5 to obtain the placenta as described by Martin and Cockrof...

ProteomicsArabidopsis thaliana whole-proteome BIN2 kinase assay
Finely ground leaf tissue of wild-type columbia-0 ecotype was used. Protein extraction was performed in buffer-saturated phenol and high sucrose buffer. Extracted proteins were incubated with purified recombinant GST or GST-BIN2 kinase. Filter-assisted sample preparation (FASP) columns in prese...

ProteomicsQuantitative proteomics reveals extensive lysine ubiquitination in Arabidopsis thaliana
In this study, we describe an antibody-based approach to enrich ubiquitinated peptides from vegetative tissues for detection via peptide mass spectrometry. This enrichment method can be coupled with isobaric labeling to enable quantification from up to 18-multiplexed samples. This approach identifie...

ProteomicsAlkylation reageant comparaison
Comparison of off target alkylation using chloroacetamide (CAA) and iodoacetamide (IAA). The peptide preparation was performed side by side, following identical methods except the alkylation treatment with either IAA or CAA. None of the comparison of off-targets on between IAA and CAA showed a signi...
