ProteomicsThe Arabidopsis tyrosine phosphatase RLPH2 targets D-group MAP kinases
Knowing that biochemically RLPH2 is a tyrosine phosphatase, we selectively In an attempt to discover RLPH2 substrates we decided to use the power of phospho-proteomics. Immunoprecipitated tyrosine phosphorylated peptides from enriched phospho-peptide pools derived from these plant extracts. Mass spe...

ProteomicsInvolvement of low molecular weight tyrosine acid phosphatase in abscisic acid signaling in Arabidopsis
Low molecular weight protein tyrosine phosphatase (LWM-PTP) is highly conserved tyrosine phosphatase from plants to animals. The function and putative targets of plant LWM-PTP homolog is not reported yet. Here, we revealed that Arabidopsis LWM-PTP homolog APH is a functional tyrosine phosphatase. AP...

TranscriptomicsTranscription profiling of Drosophila tissue expressing phosphatase mutant eya shows that reducing phosphatase activity did not globally impair transcriptional output
Drosophila eye specification an development relies on a collection of transcription factors termed the retinal determination gene network (RDGN). Two members of this network, Eyes absent (EYA) and Sine oculis (SO), form a transcriptional complex in which EYA provides the transactivation function wh...

Proteomics[HPP-2.0] A tyrosine phosphoproteome analysis approach enabled by selective dephosphorylation with protein tyrosine phosphatase
Protein tyrosine phosphorylation (pTyr) plays a prominent role in signal transduction and regulation in all eukaryotic cells. In conventional immunoaffinity purification (IP) methods, phosphotyrosine peptides are isolated from the digest of cellular protein extracts with a phosphotyrosine-specific a...

ProteomicsA Global Analysis of Receptor Tyrosine Kinase – Protein Phosphatase Interactome
Receptor tyrosine kinases (RTKs) and protein phosphatases comprise protein families that play crucial roles in cell signaling. However, a comprehensive picture of how RTKs functionally associate with phosphatases remains elusive. We aimed to study this problem by using two protein-protein interactio...

ProteomicsPeptide probes containing a non-hydrolyzable phosphotyrosine-mimetic residue as a tool for tyrosine phosphatomics
Protein tyrosine phosphatases (PTPs) cooperate with protein tyrosine kinases to regulate intracellular tyrosine phosphorylation levels, and their dysfunction is associated with various diseases. However, due to the low abundance of PTPs in cells, comprehensive analysis requires an enrichment step pr...

TranscriptomicsRNA-seq analysis of IL-10 treatment of wildtype and Ptpn1-/- knockout peritoneal macrophages
We report here the deep sequencing of the mRNA from peritoneal exudate cells (macrophages) purified from wildtype or Ptpn1 (PTP1B) knockout mice, either treated or untreated with IL-10. In periotenal macrophages IL-10 activates the transcription factor STAT3 to execute and anti-inflammatory gene exp...

TranscriptomicsRNA polymerase II termination involves CTD tyrosine dephosphorylation by CPF subunit Glc7
At the 3'-ends of genes, RNA polymerase (Pol) II is dephosphorylated at tyrosine 1 residues of its C-terminal domain (CTD), resulting in recruitment of transcription termination factors. We show that the multisubunit cleavage and polyadenylation factor (CPF) is a Pol II CTD phosphatase and its Glc7 ...
