Annotated paper:	Zhang ZY, et al. "Ubiquitination and functional modification of GluN2B subunit-containing NMDA receptors by Cbl-b in the spinal cord dorsal horn" Sci Signal. 2020 Jun 30;13(638):eaaw1519 PMID:32606037
Figure(s):	Figures 1-4
Annotation description:	Figure 1b: confocal imaging of immunofluorescence labeling for Cbl-b and PSD-95 (DLG4) in cultured spinal cord dorsal horn neurons showed partial co-localization. Imaging resolution was too low to pinpoint precise synaptic localization. Figure 2: Cbl-b specifically interacts with NMDAR subunit GluN2B (GRIN2B) in co-immunoprecipitations from spinal cord dorsal horn of adult mice and HEK293T cells. Figure 3: Cbl-b enhanced the ubiquitination and reduced the surface expression of GluN2B in spinal neuron cultures and HEK293T cells. Figure 4: Cbl-b promotes the developmental decline of synaptic GluN2B receptors.
