Multiple enhancers in physical proximity can reinforce shared transcriptional 'hubs' to preserve their transcriptional output, providing a buffer during environmental stresses and genetic perturbations to preserve phenotypic robustness.
In multi-channel sensory systems, gain adaptation can help maintain not only coding capacity across changes in signal intensity, but also combinatorial representations of odor identity.

Enhancements to the CUT&RUN antibody-targeted nuclease strategy for chromatin profiling include an improved affinity-cleavage fusion protein and digestion protocol, and a simplified calibration strategy.
Systematic in vivo analysis reveals the divergent engagement of Plexin B structural motifs in distinct neurodevelopmental processes and a regulatory role of convertase cleavage in Plexin B signaling.
Recruitment of HOPS tethering complex to target membranes to promote vesicle fusions requires proper complex assembly and specific small GTPases, and HOPS is not transformed from the related miniCORVET complex.

Absolute quantification of CTCF and cohesin reveals quantitative constraints on 3D genome organization and illuminates the molecular architecture of the cohesin complex.
Unlike Chd1, ISWI remodelers preferentially shift asymmetric nucleosomes toward the side possessing a wild type acidic patch, regardless of DNA lengths flanking the nucleosome.
Embryonic PI3K-Yap activity regulates apical adhesion and proliferation of neural progenitors lining the lateral ventricular surface, to maintain the smooth, non-folded mouse brain and to prevent developmental hydrocephalus.
