Gromova et al., 2018 reported that KIF21B, in conjunction with NBEA, regulates the cell surface expression of GluN2B-containing NMDARs, and that KIF21B-null mice exhibited decreased social approach and impaired social recognition. KIF21B-null mice had previously been shown to display deficits in learning and memory (Muhia et al., 2016) and hypoplasia of the corpus callosum (Kannan et al., 2017).
Molecular Function
Plus-end directed microtubule-dependent motor protein which displays processive activity. Is involved in regulation of microtubule dynamics, synapse function and neuronal morphology, including dendritic tree branching and spine formation. Plays a role in lerning and memory. Involved in delivery of gamma-aminobutyric acid (GABA(A)) receptor to cell surface.
