    Calsyntenin-1 Affects Trafficking of
    NMDA Receptor Subunits
    Jeanne Ster, Martin Steuble, Clara Orlando,
    Tu-My Diep, Alexander Akhmedov, et al.
    (see pages 8716–8727)
    Membrane proteins are transported in vesicles
    that are carried along microtubules by
    motor proteins. Motors interact with vesicles
    by binding to adaptor proteins such as
    calsyntenin-1, which couples vesicles to
    kinesin-1 and is associated with early and
    recycling endosomes. Previous studies suggested
    a role for calsyntenins in synaptic
    plasticity, prompting Ster et al. to examine
    the effects of truncating calsyntenin-1 in
    mice to prevent its interaction with kinesin.
    In the hippocampus of juvenile mutant
    mice, the frequency and slope of spontaneous
    EPSPs were reduced compared to those
    in controls, while long-term potentiation
    was enhanced. These effects were attributable
    to an increase in the synaptic levels of
    NMDA receptor GluN2B subunits at the
    expense of GluN2A subunits. GluN2A,
    GluN2B, and GluN1 subunits all colocalized
    with calsyntenin-1 in endosomes, suggesting
    the trafficking of all three subunits
    involves calsyntenin-1. However, the timing
    of calsyntenin-1 expression and the effects
    of the mutation suggest that calsyntenin-1 is
    especially important for the postnatal increase
    in GluN2A expression.
