Genomic imprinting in the bryophyte Marchantia polymorpha by Polycomb results in maternal dominance of embryonic gene expression.

UBX proteins reduce the ubiquitin threshold of mammalian p97-UFD1-NPL4.

In vitro single-particle tracking reveals that ATP binding increases the one-dimensional diffusion of yeast chromatin remodeler SWR1 on DNA stretched between optical tweezers and diffusion is confined by protein roadblocks and nucleosomes.

Examination of the changes in the transcription start site selection in TCL1-driven chronic lymphocytic leukemia and their impact on mRNA translation revealed a marked elevation of intra-genic cryptic promoters, which are predicted to generate multiple N-terminally truncated or modified proteins.

A critical analysis of recent single-cell transcriptomic studies of Drosophila blood cells confirms the extreme plasticity of the major phagocyte class, identifies a new class of blood cell, and suggests relationships to blood cells in other insects.

Natural genetic variation reveals how DNA sequence impacts core transcriptional processes of initiation, pause, and termination.

Auxin-inducible degradation of CRISPR-tagged endogenous proteins in mice reveals cell-type-specific dependence on the mitotic chromosome condensation proteins.

DExCon, LUXon, and DExogron approaches simultaneously block endogenous gene expression and permit tuning of re-expression levels in time and space; proof-of-principle reveals unforeseen differences in protein kinetics, cargo handling, and cell migration regulation between closely related Rab11 family members.

In a synthetic system, spreading of chromatin-mediated silencing to nearby genes depends on distance and can bypass genetic insulators, while reactivation after release of gene targeting is coordinated by insulators and promoters.

METTL18 methylates histidine 245 of ribosomal protein RPL3, retards ribosome traversal at tyrosine codons, and thus ensures nascent protein folding for proteostasis maintenance.
