Abstract:
:Many zebrafish transcription factors have been isolated, and the challenge at present is to uncover the genes and pathways they regulate. The wealth of developmental mutants available for study and recent advances in zebrafish transgenic technology have allowed identification of putative transcriptional regulatory pathways, as well as characterization of promoter interactions at a molecular level.
