ProteomicsMotif-centric phosphoproteomics to target kinase-mediated signaling pathways
Identifying cellular phosphorylation pathways based on kinase-substrate relationships is a critical step to understanding the regulation of physiological functions in cells. Mass spectrometry-based phosphoproteomics workflows have made it possible to comprehensively collect information on individual...

ProteomicsAurora B opposes PP1 function in mitosis through phosphorylation of the conserved RVxF binding motif in PP1 regulatory proteins
Protein phosphatase 1 (PP1) is a highly conserved protein phosphatase that opposes the actions of a diverse set of Ser-Thr protein kinases by controlling the majority of serine-threonine (Ser-Thr) dephosphorylation reactions in eukaryotes. PP1 gains substrate specificity through binding to a large n...

Proteomics,MultiomicsProtein phosphorylation evolution across 18 fungal species
Protein phosphorylation evolution across 18 fungal species. For each species whole cell extracts were digested separately with trypsin and LysC. Each digest was IMAC enriched and analyzed by LC-MS/MS in technical triplicate on an LTQ Orbitrap Velos using a 120min method. Data was searched against th...

TranscriptomicsEffects of PGRMC1 phosphorylation on genome integrity and epigenetics
Progesterone receptor membrane component 1 (PGRMC1) is a protein that has been implicated in cancer biology and poor patient outcomes, which can be over-expressed in cancers, and exist in alternative states of phosphorylation.Here, we show that manipulation of PGRMC1 phosphorylation by mutagenesis r...

ProteomicsIdentification of Endogenous Kinase Substrates by Proximity Labeling Combined with Kinase Perturbation and Phosphorylation Motifs
Mass spectrometry-based phosphoproteomics can identify more than 10,000 phosphorylated sites in a single experiment. But, despite the fact that enormous phosphosite information has been accumulated in public repositories, protein kinase-substrate relationships remain largely unknown. Here, we descri...

ProteomicsMotif-dependent Immune Coreceptor Interactome Profiling by Photoaffinity Chemical Proteomics
The identification of tyrosine phosphorylation-dependent interactome of immune coreceptors is crucial for the understanding of signal pathways involved in immunotherapy. However, identifying motif-specific interactome for each tyrosine phosphorylation site commonly found on these multi-phosphorylate...

TranscriptomicsAnalysis of Mouse Dendritic and Antigen presenting cell and Mouse autoimmune and Inflammatory Response
Antigen presenting cells (APC) express receptors recognizing microbes and regulating immune responses by binding to corresponding ligands on immune cells. Having discovered a novel inhibitory pathway triggered by ligation of DC-HIL on APC to a heparin/heparan sulfate-like saccharide of syndecan-4 o...
