The intrinsically disordered N-terminus of Sfr1 contains two Rad51 binding sites that facilitate Rad51 filament stabilization and ATPase stimulation by the Swi5-Sfr1 complex, leading to efficient Rad51-driven strand exchange.
Postsynaptic MT1-MMP serves as a molecular switch to synaptogenesis by clearing the surrounding ECM environment that allows effective deposition of nerve-derived synaptogenic factors to induce postsynaptic differentiation at developing NMJs.
Structural brain plasticity is encoded in the topographic distribution of Toll receptors and their ability to switch between alternative signalling outcomes, thus translating diverse sensory experience into structural change.
Hedgehog-pathway activation in adjacent epithelial and stromal cells, but not in epithelial or stromal cells alone, enables the generation of functional de novo hair follicles in unwounded adult mouse skin.
Evolutionary adaptation to a constitutive perturbation of DNA replication reveals that adaptive mutations in three conserved pathways interact to restore faithful chromosome replication and segregation.
