Structure and transcription of the gene for translation elongation factor 1 subunit alpha of zebrafish (Danio rerio)

The zebrafish gene for translation elongation factor 1 alpha (EF1 alpha) was isolated from a phage Lambda genomic library and sequence and structure determined. One gene copy of EF1 alpha per haploid set of chromosomes was found and no processed pseudogenes. A highly active promoter region was localized to a 277 bp PstI/PvuII fragment beginning 240 bp upstream from the tsp, but no transcription enhancing, or silencing activity was observed within 1 kbp upstream, or downstream from the promoter. Expression of EF1 alpha appears to be developmentally regulated.
