Building on previous work (Syrjänen, Pellegrini, & Davies, 2014), it is shown that SYCP3 contributes to the architecture of meiotic chromosomes through local bridging interactions that result in large-scale compaction of the chromosome axis.
The kinase that controls maternal mRNA translation is regulated by phosphorylation of its activating subunit to restrict kinase activity to the developmental window between meiosis completion and early embryogenesis.
The strength of pattern completion during memory retrieval, indexed by hippocampal activity and cortical reinstatement, explains within- and across-individual variability in episodic memory in older adults.
The structure of the VemP-stalled ribosome reveals a helix-double turn-helix conformation of the nascent chain within the ribosomal tunnel, illustrating how secondary structure formation directly at the peptidyltransferase center of the ribosome can induce translational arrest.
Condensation and segregation of chromosomes during mitosis is caused by a combination of short-range interactions between nucleosomes and the long-range contraction of chromosome arms mediated by condensin.
