Figure(s):Figure 7
Annotation description:Figure 7: immunofluorescence imaging of 21DIV cultured hippocampal neurons showed RNF34 co-localization with inhibitory synapse marker proteins GABA-A-gamma2 and GAD.

Figure 8: immunogold EM of rat brain cerebellum showed RNF34 localization to both pre- and post-synapses of GABAergic synapses. Postsynaptic localization was observed at or adjacent to the postsynaptic specialization. Presynaptic localization appeared both at the active zone and further from the active zone / plasma membrane.

"The EM immunogold data are consistent with the notion that RNF34 is localized at synapses (pre- and post-synaptically), nonsynaptic membranes, and cytoplasm, probably at cytoplasmic organelles such as endosomes. Thus, the immunofluorescence and immunogold data show that although RNF34 is not exclusively localized at GABAergic synapses, the latter frequently show the presence of RNF34. GABAAR clusters frequently have RNF34 associated with them."
