Escherichia coli is surprisingly tolerant to chromatinization by archaeal histones, suggesting that histones can become established as ubiquitous chromatin proteins without interfering critically with some key DNA-templated processes.
An ensemble of the ubiquitin-activating enzyme UBA6 and ubiquitin-conjugating enzyme/ubiquitin-ligase BIRC6 mediates ubiquitination of LC3, targeting the latter for proteasomal degradation and thus attenuating autophagic degradation of cellular substrates.
Identification and characterization of multiple brain clusterin isoforms, including a mitochondrial matrix-targeted isoform, provides foundation to potentially clarify the link between these proteins and the development of late-onset Alzheimer’s disease.
Using a suite of CRISPR technologies, unique chemical tools, and carefully designed biochemical and cell biological assays, we define the mechanism of action of Retro-2, an inhibitor of retrograde toxins.
The innate immune DNA sensor IFI16 is in association with H3K9 methyltransferases SUV39H1 and GLP under physiological conditions in the nucleus which facilitates the epigenetic silencing of foreign viral DNA.
