    Inhibition of protein synthesis in M1 of monkeys disrupts performance of sequential movements guided by memory

    Machiko Ohbayashi
    Inhibition of protein synthesis in primary motor cortex (M1) of monkeys disrupted the performance of skilled sequential movements suggesting that M1 is involved in maintenance of skilled sequential movements.

    Active presynaptic ribosomes in the mammalian brain, and altered transmitter release after protein synthesis inhibition

    Matthew S Scarnati, Rahul Kataria ... Kenneth G Paradiso
    Local presynaptic protein synthesis occurring at established nerve terminals in the mammalian brain provides a mechanism for rapidly controlling or restoring presynaptic proteins that affect neurotransmitter release and presynaptic efficiency.

    New learning while consolidating memory during sleep is actively blocked by a protein synthesis dependent process

    Roi Levy, David Levitan, Abraham J Susswein
    The brain inhibits the formation of new memories just after waking to safeguard the ongoing stabilization of existing memories during sleep.

    Increased cortical plasticity leads to memory interference and enhanced hippocampal-cortical interactions

    Irene Navarro Lobato, Adrian Aleman-Zapata ... Lisa Genzel
    Increasing cortical plasticity leads to better one-trial memory but more interference effects on semantic-like memory.

    In vitro analysis of RQC activities provides insights into the mechanism and function of CAT tailing

    Beatriz A Osuna, Conor J Howard ... David E Weinberg
    Yeast extracts recapitulate a quality-control pathway dedicated to rescuing stalled ribosomes, providing unexpected insights into a noncanonical elongation reaction and the fate of incompletely synthesized proteins.

    Distinct stages of the translation elongation cycle revealed by sequencing ribosome-protected mRNA fragments

    Liana F Lareau, Dustin H Hite ... Patrick O Brown
    The size of the mRNA fragment protected by a ribosome depends on the ribosome's conformation, which enables studies of the distinct steps of decoding and translocation at single-codon resolution.

    Minor introns are embedded molecular switches regulated by highly unstable U6atac snRNA

    Ihab Younis, Kimberly Dittmar ... Gideon Dreyfuss
    Hundreds of cell growth and stress response genes are controlled by a rare small RNA component of an ancient splicing machinery, providing a raison d'être for its previously unexplained evolutionary conservation.

    All-trans retinoic acid induces synaptic plasticity in human cortical neurons

    Maximilian Lenz, Pia Kruse ... Andreas Vlachos
    The vitamin A derivative, all-trans retinoic acid, induces protein-synthesis-dependent synaptic plasticity in the human brain.

    Role of protein synthesis and DNA methylation in the consolidation and maintenance of long-term memory in Aplysia

    Kaycey Pearce, Diancai Cai ... David L Glanzman
    Behavioral and synaptic investigations of long-term memory in Aplysia reveal differing roles for DNA methylation, protein synthesis during training and protein synthesis shortly after training with respect to memory consolidation and maintenance.
