Our findings are consistent with a role for NEEP21 in facilitating vesicular transport of GluR2 between intracellular compartments and the postsynaptic plasma membrane.
Title: Neuronal enriched endosomal protein of 21 kDa colocalizes with glutamate receptor subunit GLUR2/3 at the postsynaptic membrane.
We identify the neuronal-specific endosomal protein NEEP21 (neuron-enriched endosomal protein of 21 kD) as a regulator of L1/NgCAM sorting in somatodendritic endosomes.
Title: The somatodendritic endosomal regulator NEEP21 facilitates axonal targeting of L1/NgCAM.
the essential role of NEEP21 in the recycling mechanism; this protein acts at the level of early endosomes to promote sorting of receptors toward a recycling pathway
Title: Crucial role of neuron-enriched endosomal protein of 21 kDa in sorting between degradation and recycling of internalized G-protein-coupled receptors.
Together, we conclude that NEEP21 contributes to the regulation of synaptic transmission and plasticity in slice cultures by affecting the recycling and targeting of AMPA receptors to the synapse.
Title: The endosomal protein NEEP21 regulates AMPA receptor-mediated synaptic transmission and plasticity in the hippocampus.
about 85-kDa protein kinase phosphorylates GRIP1 on serine 917. This kinase is present in NEEP21 immunocomplexes and is activated in okadaic acid-treated neurons
Title: Phosphorylation of glutamate receptor interacting protein 1 regulates surface expression of glutamate receptors.
NEEP21-GRIP1 binding is crucial for GluR2-AMPAR sorting through endosomes and their recruitment to the plasma membrane, providing a mechanism to differentially regulate AMPAR subunit cycling in internal compartments.
Title: Interactions between NEEP21, GRIP1 and GluR2 regulate sorting and recycling of the glutamate receptor subunit GluR2.
NEEP21 is a neuronal protein that is localized to the early endosomal pathway and is necessary for correct receptor recycling in neurons.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
