TranscriptomicsUBL5 is essential for pre-mRNA splicing and sister chromatid cohesion in human cells
UBL5 is an atypical ubiquitin-like protein, whose function in metazoans remains largely unexplored. We show that UBL5 is required for sister chromatid cohesion maintenance in human cells. UBL5 primarily associates with spliceosomal proteins, and UBL5 depletion decreases pre-mRNA splicing efficiency,...

ProteomicsGain-of-function mutations amplify cytotoxic FAM111 protease activity in poikiloderma, gracile bone dysplasia and Kenny-Caffey syndromes
Dominant missense mutations in the human serine protease FAM111A underlie perinatally lethal gracile bone dysplasia and Kenny-Caffey syndrome 1-3, yet how FAM111A mutations lead to disease is not known. We show that FAM111A proteolytic activity suppresses DNA replication and transcription by displac...

ProteomicsK27-linked ubiquitylation promotes p97 substrate processing and is essential for cell proliferation
Conjugation of ubiquitin (Ub) to numerous substrate proteins regulates virtually all cellular processes. Eight distinct ubiquitin polymer linkages specifying different functional outcomes are generated in cells. However, the roles of some atypical poly-ubiquitin topologies, in particular linkages vi...

ProteomicsProfiling linkage-specific ubiquitin chain functions reveals a key role of K29-linked ubiquitylation in epigenome maintenance
We applied a cell-based Ub replacement strategy enabling specific, conditional abrogation of each of the seven lysine-based Ub chain types in human cells to comprehensively profile global ubiquitylation changes resulting from disabling formation of individual Ub chain types. Focusing on K29-linked u...

ProteomicsProteomics reveals dynamic assembly of repair complexes during bypass of DNA cross-links part 2 of 2: AP-MS DATA (QUBIC)
DNA interstrand crosslinks (ICLs) block replication fork progression by inhibiting DNA strand separation. Repair of ICLs requires sequential incisions, translesion DNA synthesis, and homologous recombination, but the full set of factors involved in these transactions remains unknown. Here we establi...

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...
