ProteomicsE2/E3-independent ubiquitin-like protein conjugation by Urm1 is directly coupled to cysteine persulfidation
Posttranslational modifications by ubiquitin-like proteins (UBL) are essential for nearly all cellular processes. Ubiquitin related modifier 1 (Urm1) is a non-canonical UBL which plays a key role in tRNA anticodon thiolation as a sulfur carrier protein (SCP). While Urm1 has also been observed to con...

TranscriptomicsThe conserved ubiquitin-like protein Hub1 plays a critical role in splicing in human cells
Different from canonical ubiquitin-like proteins, Hub1 does not form covalent conjugates with substrates but binds proteins non-covalently. In Saccharomyces cerevisiae, Hub1 associates with spliceosomes and mediates alternative splicing of SRC1, without affecting pre-mRNA splicing generally. Human H...

ProteomicsUbiquitination at the Parkin ubiquitin-like domain suggests a new mechanism for Parkin activation
The mitochondrial kinase PINK1 and the cytosolic ubiquitin ligase (E3) Parkin is involved in mitochondrial quality control. PINK1, which phosphorylates ubiquitin at serine 65 residue and the ubiquitin-like (Ubl) domain of Parkin at serine 65 residue, promotes the Parkin activation and translocation ...

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...

ProteomicsProteome-wide analysis of SUMO2 targets in response to pathological DNA replication stress in human cells
SUMOylation is a form of post-translational modification involving covalent attachment of SUMO (Small Ubiquitin-like Modifier) polypeptides to specific lysine residues in the target protein. In human cells, there are four SUMO proteins, SUMO1–4, with SUMO2 and SUMO3 forming a closely related subfami...

GenomicsGenome-wide analysis of insulin-like growth factor 1 receptor (IGF1R) binding sites in DFB cells
The insulin-like growth factor 1 receptor (IGF-1R) plays crucial roles in developmental and cancer biology. Most of its biological effects have been ascribed to its tyrosine kinase activity. We report that IGF-1 promotes the modification of IGF-1R by small ubiquitin-like modifier protein-1 (SUMO-1) ...

ProteomicsUbiquitin Proteomics Analysis of Systemic Sclerosis Lung Fibroblasts with or without KLHL42 knockdown
Systemic scleroderma (SSc) is an autoimmune disease which results in fibrotic production in the lung. Resultant SSC-pulmonary fibrosis is the main cause of mortality among SSc patients. From high throughput RNAi screening, we uncovered the ubiquitin E3 ligase KLHL42 as a potential pro-fibrotic media...

TranscriptomicsThe histone H2B ubiquitin ligase RNF20 is required for MLL-rearranged leukemia
MLL-fusions are potent oncogenes that initiate aggressive forms of acute leukemia. As aberrant transcriptional regulators, MLL-fusion proteins alter gene expression in hematopoietic cells through interactions with the histone H3 lysine 79 (H3K79) methyltransferase DOT1L. Notably, interference with M...

TranscriptomicsPost-transcriptional fine-tuning of COP9 signalosome subunit biosynthesis is regulated by the c-Myc/Lin28B/let-7 pathway
The COP9 signalosome (CSN) is a conserved protein complex occurring in all eukaryotes. The mammalian CSN consists of eight subunits (CSN1 – CSN8) and possesses an intrinsic metalloprotease JAMM motif localised to CSN5. In addition, it is associated with kinases such as protein kinase CK2 and D and t...
