Creating a bacterium that forms eukaryotic nucleosome core particles

Nature Communications
The nucleosome is one of the hallmarks of eukaryotes, a dynamic platform that supports many critical functions in eukaryotic cells. Here, we engineer the in vivo assembly of the nucleosome core in the model bacterium Escherichia coli.

pyDiSCaMB: enabling the use of multipolar scattering factors in Phenix

Journal of Applied Crystallography, EarlyView.
pyDiSCaMB provides an interface between cctbx and DiSCaMB. The former drives Phenix and the latter provides multipolar parameterization of scattering, thus enabling multipolar modelling in Phenix.Multipolar scattering models, such as the transferable aspherical atom model, account for atomic chemical interactions and provide a more accurate ...

Free energy profile for unwrapping outer superhelical turn of CENP-A nucleosome

Biophysics and Physicobiology, 2019
Eukaryotic genome is packaged in a nucleus in the form of chromatin. The fundamental structural unit of the chromatin is the protein-DNA complex, nucleosome, where DNA of about 150 bp is wrapped around a histone core almost twice.

Nucleosome Positioning Assay

Bio-Protocol, 2017
The basic unit of chromatin is the nucleosome, a histone octamer with 147 base pairs of DNA wrapped around it. Positions of nucleosomes relative to each other and to DNA elements have a strong impact on chromatin structure and gene activity and are ...

Identification of MEF2A, MEF2C, and MEF2D interactomes in basal and Fsk‐stimulated mouse MA‐10 Leydig cells

Andrology, EarlyView.
Abstract Background Myocyte enhancer factor 2 transcription factors regulate essential transcriptional programs in various cell types. The activity of myocyte enhancer factor 2 factors is modulated through interactions with cofactors, chromatin remodelers, and other regulatory proteins, which are dependent on cell context and physiological state.

Proteomic profile of CSF obtained at the time of diagnosis determines amyotrophic lateral sclerosis progression and survival: CXCL7 levels in disease prognosis and survival

Brain Pathology, EarlyView.
Untargeted multiomic profiling of cerebrospinal fluid reveals that proteomic, but not lipidomic, signatures robustly distinguish ALS patients from controls and stratify individuals by survival, highlighting marked molecular differences between short survival and long survival disease.

Intrinsic specificity of a ‘core’ TIP60 acetyltransferase complex in Drosophila

The FEBS Journal, EarlyView.
The intrinsic substrate selectivity of the Drosophila TIP60‐core acetyltransferase was determined using synthetic nucleosome arrays. Targeted mass spectrometry revealed site‐specific acetylation of histones H2A, H2A.V, and H4, uncovering distinct acetylation rates and patterns across individual lysines.

Proteostasis of organelles in aging and disease

The FEBS Journal, EarlyView.
Cells rely on regulated proteostasis mechanisms to keep their internal compartments functioning properly. When these mechanisms fail, damaged proteins accumulate, disrupting organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi, and lysosomes, as well as membraneless organelles, such as stress granules, processing bodies, the ...

Current perspectives on KMT2A fusion proteins and menin inhibition in paediatric acute myeloid leukaemia

The FEBS Journal, EarlyView.
Genetic rearrangements resulting in the expression of KMT2A fusion alleles can lead to dramatic transcriptional disturbances that contribute to the onset of acute leukaemias. Fortunately, menin inhibition has emerged as a promising new class of targeted therapy.

Tissue Resident Memory Cells: Friend or Foe?

Immunology, EarlyView.
Tissue‐resident memory T cells (TRM cells) are specialised immune cells in barrier tissues like the lungs, skin and gut, providing rapid host defence and tumour surveillance. Their retention and differentiation are regulated by molecules such as CD69, CD103 and TGF‐β. Dysregulation of TRM cells can lead to chronic activation, driving conditions such as
