Figure 6.
Synapsin immunoreactivity and SV numbers were significantly reduced in nwk2 mutant synaptic boutons. (a–d) Mab-Synapsin immunoreactivity in nwk2 mutant synaptic boutons (b) appeared to be weaker than CS (a), eag1 (c) or eag1;nwk2. (e–f) Ultrastructural analysis of SVs near T-AZs showed fewer SVs in nwk2 (f), eag1 (g) or eag1;nwk2(h) compared with CS (d). (i) The SV numbers in RRP (0–200 nm) or RP (200–400 nm) from a T-AZ in nwk2 mutant synaptic boutons were significantly reduced. (j) Mab-Synapsin coprecipitated with Nwk, DSypt1 and Synapsin from protein extracts from larval body wall muscle preparations. Characters above error bars indicate groups that are statistically identical.
