Annotation description:"Previous immunogold EM studies have shown that the biosynthetic enzyme of 2-AG is selectively localized to the postsynaptic plasma membrane (Katona et al., 2006; Yoshida et al., 2006). In contrast, the present quantitative analysis of immunogold particle distribution at high resolution found that NAPE-PLD was not associated with the plasma membrane, but rather accumulated on the external surface of intracellular membrane compartments (Fig. 4 A1-B). Furthermore, the majority of gold particles were attached to cisternae of smooth endoplasmic reticulum (SER) (median, 58.08%; range, 52.63-62%; n = 352 gold particles; n = 4 animals) (Fig. 4 C)."

Figure 3: "Immunogold particles (arrows) representing the precise subcellular localization of NAPE-PLD are found presynaptically in excitatory axon terminals both in the stratum radiatum (in Schaffer collaterals; b in C) and in the hilus (mossy terminals; b in E), whereas postsynaptic structures [dendritic spines (sp) in C and thorny excrescences (te) in E] are immunonegative."

Figure 4: "A, High magnification of serial sections from a mossy fiber terminal demonstrates that NAPE-PLD is present on cisternae of SER, but rarely on synaptic vesicles or on the plasma membrane. B, A similar subcellular localization is found in Schaffer collaterals in CA1. C, Quantitative analysis of subcellular immunogold distribution confirms the preferential localization of NAPE-PLD on cisternae of SER."
