At 24 hours post-fertilization (hpf), detected in the somites, tail bud region adjacent to the fin fold, pectoral fin buds and the head. A similar expression pattern is observed at 48 hpf, although levels are reduced. By 120 hpf, expression is almost completely undetectable. Morpholino knockdown of the protein has no visible phenotype. Morpholino knockdown in animals homozygous for the c14 allele suppresses the c14 phenotype.
