Fig 6. Cspg4 transmembrane domain mutant embryo phenocopied cspg4 overexpression phenotype.
(A) Scheme illustrates wild-type and mutant Cspg4 protein structure. (B) The flag-tag signal of both wild-type and mutant Cspg4 were detected in the cell lysate, but in culture medium the signal of flag-tag was only detected in mutant Cspg4-flag transfected group. (C) Eight percent of cspg4 em1twu0405 embryos were cyclopia. (D) Four percent of cspg4 em1twu0405 embryos showed midline bifurcation (notochord was indicated by asterisk).
