Annotation description:[Fig.4: "NOS1AP and Scrib colocalize to synaptophysin-positive presynaptic specializations in axons."
- "Together with our results showing that Scrib associates with presynaptic proteins, these localization data suggest that NOS1AP localizes with Scrib to presynaptic specializations, where it may play a role in synaptic vesicle dynamics and active zone formation."]

Fig.5: "NOS1AP and Scrib colocalize in dendrites"
- "We cotransfected dissociated rat hippocampal neurons with constructs encoding YFP-NOS1AP, CFP-Scrib, and RFP-synaptophysin. We saw colocalization of all three markers, supporting the notion that NOS1AP and Scrib could play a role presynaptically (Fig. 4G-J, arrows). This analysis showed colocalization of YFP-NOS1AP and actin in spine heads (Fig. 5K-M, arrows), supporting the notion that NOS1AP is found in dendritic spines. Together, these data suggest that NOS1AP and Scrib proteins can localize postsynaptically in dendritic spines."
