"UNC-13L staining remains at synapses in
unc-104 mutants (Figure 8), suggesting that it is not transported to synapses by the UNC-104 protein, and therefore is unlikely to be on synaptic vesicles... In an adult
unc-104 mutant, staining of anti-UNC-13L is somewhat less intense but remains synaptic, whereas anti-UNC-17/VAChT is now localized in neuronal cell bodies"
