Annotated paper:Cheng A, et al. "ATM and ATR play complementary roles in the behavior of excitatory and inhibitory vesicle populations" Proc Natl Acad Sci U S A. 2018 Jan 9;115(2):E292-E301 PMID:29279380
Figure(s):Figure S5
Annotation description:Figure 5: confocal and super-resolution immunofluorescence imaging of ATR in 21DIV cultured cortical neurons showed co-localization with Clathrin and β-adaptin at synaptic puncta.

Figure 6, S5: super-resolution microscopy showed ATR co-localized with PSD95 (DLG4) and chromogranin-A (a DCV marker), but also in close proximity to Bassoon (BSN) in 21DIV cultured cortical neurons.

Figure 7, S6: super-resolution microscopy showed ATR co-localized with VGAT but not VGLUT in 21DIV cultured cortical neurons. ATR pulldowns yield VGAT but not VGLUT.

authors summarise;
"Taken together, these data strongly suggest that ATM is located in association with excitatory vesicles, while ATR is associated with inhibitory vesicles, consistent with their differential effects on the E/I balance in our cultures."
