Liquid–Liquid Phase Separation in Major Hallmarks of Cancer
Cell Proliferation, EarlyView.Aberrant condensates formed through phase separation are involved in the dysregulation of various critical cellular processes, including genome stability, transcriptional regulation and signal transduction, thereby promoting malignant transformation and the acquisition of multiple cancer hallmarks.

MMS21/HPY2 and SIZ1, two Arabidopsis SUMO E3 ligases, have distinct functions in development.
PLoS ONE, 2012 The small ubiquitin related modifier (SUMO)-mediated posttranslational protein modification is widely conserved among eukaryotes. Similar to ubiquitination, SUMO modifications are attached to the substrate protein through three reaction steps by the E1 ...

Role of the Bifunctional Aminoacyl-tRNA Synthetase EPRS in Human Disease [PDF]
, 2020 Aminoacyl-tRNA synthetases (AARS) are a class of enzymes that catalyze the charging of tRNAs with cognate amino acids, a critical step that contributes to the fidelity of protein synthesis.

Human FASTK preferentially binds single‐stranded and G‐rich RNA
The FEBS Journal, EarlyView.Although FASTK is known to play a role in mRNA biology, the mechanism through which it recognizes RNA has yet to be unraveled. Here, we used purified human FASTK to characterize its RNA‐binding properties in vitro. We found that FASTK prefers ssRNA oligonucleotides containing guanines with the potential to form G‐quadruplexes and binds robustly to any ...

The polySUMOylation axis promotes nucleolar release of Tof2 for mitotic exit
Cell ReportsSummary: In budding yeast, the nucleolus serves as the site to sequester Cdc14, a phosphatase essential for mitotic exit. Nucleolar proteins Tof2, Net1, and Fob1 are required for this sequestration.

Writing and erasing MYC ubiquitination and SUMOylation
Genes and Diseases, 2019 The transcription factor c-MYC (MYC thereafter) controls diverse transcription programs and plays a key role in the development of many human cancers. Cells develop multiple mechanisms to ensure that MYC levels and activity are precisely controlled in ...

Regulation of axon repulsion by MAX-1 SUMOylation and AP-3. [PDF]
, 2018 During neural development, growing axons express specific surface receptors in response to various environmental guidance cues. These axon guidance receptors are regulated through intracellular trafficking and degradation to enable navigating axons to ...

The FEBS Journal, EarlyView.Using cryo‐EM combined with biochemical and genetic approaches, we mapped the interaction surface between NifL and NifA to gain insights into the regulation of nitrogen fixation genes in A. vinelandii. Our findings suggest that NifL, a homolog of histidine kinases lacking phosphorylation activity, evolved to act as a steric block of NifA activity ...

Proteomic Study of SUMOylation During Solanum tuberosum–Phytophthora infestans Interactions
Molecular Plant-Microbe Interactions, 2017 Invasive plant pathogens have developed the ability to modify the metabolism of their host, promoting metabolic processes that facilitate the growth of the pathogen at the general expense of the host.
