Fig. 3. Pseudokinase STRD-1 functions cell- autonomously in neurons. (A)The expression of a Pstrd-1-nls::gfp reporter in the pharynx, excretory canal and the entire nervous system. (B)Cell-autonomous rescue of the neuronal polarity defect in
strd-1 mutants. The VD polarity defect in
strd-1(
rr91) mutant animals was fully rescued by the expression of STRD-1 solely in GABAergic neurons under Punc-25. STRD-1(D175A) also fully rescued the VD polarity defect. Values are means ± s.d.; ***, P<0.001; N.S., not significant, Wilcoxon rank- sum test; n≥10 per strain. (C)Cell-autonomous rescue of
strd-1 synaptic organization defect.
strd-1(
ok2283) mutants (i) expressing STRD-1 (ii) or STRD-1(D175A) (iii) in GABAergic neurons showed rescued juIs1 morphology. Distribution of the juIs1 punctum widths showed significantly reduced kurtoses in the rescued animals (P<0.001,
strd-1 versus either STRD-1- expressing lines, t-test; n>80 per strain). x-axis, punctum width in pixels; y-axis, density in arbitrary units. (D)Sub-cellular localization of GFP-tagged, functional STRD-1 in GABAergic neurons. GFP::STRD-1 localized to the cytoplasm and the nucleus as well as along both nerve cords. Scale bars: 5um.
