Loss of rab3-GEF results in a phenotype indistinguishable from the rab3 mutant.
Our findings suggest that although Rab3-GEF acts upstream of Rab3 to control Rab3 localization and likely GTP-binding, it also acts downstream to regulate active zone development, potentially as a Rab3 effector at the synapse.
