Mutation of the gene encoding the Mediator component thyroid hormone receptor-associated protein (TRAP)230/MED12 affects the development of multiple systems in zebrafish embryogenesis. We isolated two ethylnitrosourea-induced alleles in the gene encoding this protein and named the locus kohtalo ( kto ) after the homologous locus in Drosophila . Homozygous kto mutant zebrafish embryos show defects in brain, neural crest, and kidney development and die at ≈6 days postfertilization. In the affected tissues, differentiation is initiated and many cell type-specific genes are expressed, but there is a failure of morphogenesis and failure to complete differentiation. These results suggest that critical targets of TRAP230 function may include proteins important for cell mobility, cell sorting, and tissue assembly.
