Abstract We have designed a zebrafish genomic microarray to identify DNA-protein interactions in the proximal promoter regions of over 11 000 zebrafish genes. Using these microarrays together with chromatin immunoprecipitation with an antibody directed against tri-methylated lysine 4 of Histone H3 we demonstrate the feasibility of this method in zebrafish. This approach will allow investigators to determine the genomic binding locations of DNA interacting proteins during development and expedite the assembly of the genetic networks that regulate embryogenesis. Background As the development of an organism proceeds from the fertilized egg to multicellular embryo .
