Forkhead activin signal transducer (FAST) is a member of the winged-helix family of DNA-binding proteins that has been implicated in mesoderm induction and left-right axis specification during embryonic development in Xenopus and mouse. We have cloned and characterized a zebrafish FAST homolog. Zebrafish fast is expressed maternally and zygotically. Transcripts start regionalizing and decline in level during gastrulation. During somitogenesis, fast is expressed bilaterally in the lateral plate mesoderm, like its mouse homolog. In addition, zebrafish fast is also expressed bilaterally in the dorsal diencephalon, where the nodal-related cyclops gene is only expressed on the left side. It remains to be demonstrated whether FAST expression in the brain can mediate Nodal-induced asymmetric development.
