ProteomicsTHEMIS is a novel substrate and allosteric activator of SHP1, playing dual roles during T cell development
By combining strategies of substrate trapping for PTPs and pupylation-based interaction tagging (PUP-IT) for protein-protein interaction, we develop a systematic proximity labeling methodology PEPSI in identifying novel substrate for PTPs. We apply this approach to SHP1 and surprisingly, identified ...

TranscriptomicsSuppressing the barley uroporphyrinogen gene by Ds activation tagging element generates developmental photosensitivity
Chlorophyll production involves the synthesis of photoreactive intermediates that are toxic when in excess due to the production of reactive oxygen species (ROS). A novel activation tagged barley mutant is described that results from antisense suppression of a uroporphyrinogen III synthase (Uros) ge...

ProteomicsProfiling FERONIA interaction proteins by Pupylation-based interacting tagging in Arabidopsis
FERONIA (FER) is a ubiquitious expressed and a plasma memberane-localized receptor-like protein kinase which modulate many biological functions. Elucidating the interacting proteins is the crucial step in understanding the molecular function of FER in regulating plant development. However, weak and...

TranscriptomicsThe tumor antigen PRAME is a substrate recognition subunit of a Cul2-based ubiquitin ligase and is associated with active NFY promoters
The human tumor antigen PRAME (Preferentially expressed antigen of melanoma) is frequently overexpressed in tumors. High PRAME levels correlate with poor clinical outcome of several cancers, but the mechanisms by which PRAME could be involved in tumorigenesis remain largely elusive. We applied prote...

TranscriptomicsHematopoietic Stem Cell Differentiation Regulated by a Single Ubiquitin Ligase: Substrate Complex
Hematopoietic stem cell (HSC) differentiation is regulated by cell-intrinsic and extrinsic cues. In addition to transcriptional regulation, post-translational regulation may also control HSC differentiation. To test this hypothesis, we visualized ubiquitin-regulated protein stability of a single tra...

TranscriptomicsDual regulation of Fbw7 function and oncogenic transformation by Usp28
Fbw7, the substrate recognition subunit of SCF(Fbw7) ubiquitin ligase, mediates turnover of multiple proto-oncoproteins and promotes its own degradation. Fbw7-mediated substrate degradation is antagonized by the Usp28 deubiquitinase. We now show, using knockout mice, that Usp28 preferentially deubiq...

ProteomicsHydrophobic tagging-assisted N-termini enrichment (HYTANE) for in-depth N-terminome analysis
The analysis of protein N-termini is of great importance for understanding the protein function and elucidating the proteolytic processing. Herein, we develop a negative enrichment strategy, termed as hydrophobic tagging-assisted N-termini enrichment (HYTANE) to achieve a global N-terminome analysis...
