Annotation description:It is demonstrated that RIM2 is required to maintain the structural integrity of the active zone. Genetic removal of active zone proteins RIM1, RIM2, ELKS1 and ELKS2 leads to a loss of Bassoon, Munc13 and Piccolo, and a reduction of RIMBP2 and Cav2.1 (Figure 1), thus showing a severe reduction of the active zone.

In line with disruption of the active zone, multiple essential functions of the presynaptic terminal are affected, including vesicle docking (figure 2), vesicle priming (figure 7), spontaneous and action potential induced fusion (figure 3 and 5) and calcium influx (figure 4).

Removal of RIM1/2 or ELKS1/2 alone is not sufficient to disrupt the active zone (figure 7).

- I have added the link to SynGO ID #116 that shows that RIM2 is itself localized to the AZ. I think this strengthens the selected term.
