Phosphatases play essential roles in normal cell physiology and diseases like cancer. The challenges of studying phosphatases have limited our understanding of their substrates, molecular mechanisms, and unique functions within highly complicate networks. Here we introduce a novel strategy using sub...

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...

Vascular endothelial protein tyrosine phosphatase (VE-PTP, PTPRB) is a receptor type phosphatase that is crucial for the regulation of endothelial junctions and blood vessel development. VE-PTP regulates vascular integrity by dephosphorylating substrates which are key players in endothelial junction...

BTK substrate profile determined by treating digest KG-1 cell lysate with alkaline phosphatase followed by recombinant BTK. Samples were enriched with PolyMac phosphoenrichment kits prior to analysis. We have organized our uploaded files into three main folders: 1. BTK KALIP MS raw files: raw mass ...

Tyrosine kinase activity profiling of metatstatic malignant melanoma and normal skin tissue samples was performed using peptide kinase arrays. All samples were run in triplicates with and withouth inhbitor PLX4032 and Sutent Malate in order to identify how tyrosine kinases responds to kinase inhibit...

Acute myeloid leukemia (AML) cells rely on phospho-signaling pathways to gain unlimited proliferation potential. Here, we used domain-focused CRISPR screening to identify the nuclear phosphatase SCP4 as a dependency in AML, yet this enzyme is dispensable in normal hematopoietic progenitor cells. Usi...

In order to screen for cellular substrates of the Bacillus subtilis BY-kinase PtkA, and its cognate phosphotyrosine-protein phosphatase PtpZ, we performed a triple SILAC-based quantitative phosphoproteome analysis. Detected tyrosine phosphorylation sites for which the phosphorylation level decreased...

B cell antigen receptor (BCR) signaling is initiated by protein kinases and limited by counteracting phosphatases that currently are less well studied in their regulation of BCR signaling. We here used the B cell line Ramos to identify and quantify human B cell signaling components. Specifically, a ...
