The interplay between the Flower Ca2+ channel and PI(4,5)P2 spatiotemporally couples synaptic vesicle exocytosis to activity-dependent bulk endocytosis and synaptic vesicle reformation from bulk endosomes.
In potassium-dependent NTPases, insertion of the activating potassium ion into the active site leads to rotation of the gamma-phosphate yielding a near-eclipsed, catalytically productive conformation of the triphosphate chain.
Shifts in the balance between nucleotide-favorable and nucleotide-unfavorable conformations of myosin motors encode duty ratios and ADP release rates, demonstrating the power of an ensemble perspective for uncovering sequence-function relationships.
Sox2 transcription is not correlated with spatial proximity of its essential regulatory enhancer in embryonic stem cells, suggesting gene transcription is not limited to periods of direct enhancer-promoter contact.
A health-system embedding method for genomic discovery and clinical characterization of disease highlights the importance of documenting a wider spectrum of genetic disorders in diverse populations.
Asc1/RACK1 promotes the translation of mRNAs associated with the translational closed loop complex, which have short open reading frames and encode proteins required for core metabolic processes.
Large regions of foreign DNA inserted into mammalian chromosomes assemble into H3K9me3-heterochromatin and result in increased condensin loading with organisation into shorter mitotic chromosome loops than endogenous DNA.
Cryo-EM reveals how the central functional site of the ribosome is assembled and provides a framework to interpret the consequences of mutations linked to leukaemia-associated ribosomopathies.
