Gating currents analysis at different Ca2+ concentrations of BK channels reveals a strong allosteric coupling between Ca2+- and voltage-sensing modules via equivalent contributions exerted by the RCK1 and RCK2 Ca2+-sites.
For many bacterial species, recombination dominates genome evolution and phylogenetic patterns that have so far been assumed to reflect clonal relationships, in fact reflect variation in recombination rates across lineages.

Binding of progesterone receptor and transcription factor PAX2 to pre-assembled permissive chromatin compartments regulates endometrial cancer gene expression under estrogenic conditions.
An MTF2-containing subcomplex of Polycomb Repressive Complex 2 promotes cell cycle progression through repression of D-type cyclin expression in certain cellular contexts.
BASH MaP quantitatively reveals alternative RNA tertiary structures by enabling dimethyl sulfate to probe the presence of nucleobase interactions on the Watson-Crick and Hoogsteen faces of single RNA molecules.
