Annotated paper:Brai E, et al. "Notch1 Regulates Hippocampal Plasticity Through Interaction with the Reelin Pathway, Glutamatergic Transmission and CREB Signaling" Front Cell Neurosci. 2015 Nov 26;9:447 PMID:26635527
Figure(s):Figure 1
Annotation description:Figure 1a: immunogold EM of hippocampal cryosections using a specific antibody against the cytoplasmic tail of Notch1 showed localization to the postsynaptic density

Figure 1c,d: Fluorescent immunolabeling on primary neuronal cultures shows that Notch1 and ApoER2 are partially co-expressed in NMDAR1 positive puncta. Similarly, dendritic (spine) puncta for Notch1 and Dab1 are observed.

Further functional assays confirm that Notch1 not only co-localized with these proteins but also interferes with the Reelin pathway and regulates NMDA transmission, adding further credibility to postsynaptic localization.

Based on the known transmembrane topology of this protein, "integral component of ... membrane" term was selected.
