Abstract
The myocyte enhancer factor (MEF) 2 family of transcription factors has been implicated in the regulation of muscle transcription in vertebrates. We have cloned a protein from Drosophila, termed D-MEF2, that shares extensive amino acid homology with the MADS (MCM1, Agamous, Deficiens, and serum-response factor) domains of the vertebrate MEF2 proteins. D-mef2 gene expression is first detected during Drosophila embryogenesis within mesodermal precursor cells prior to specification of the somatic and visceral muscle lineages. Expression of D-mef2 is dependent on the mesodermal determinants twist and snail but independent of the homeobox-containing gene tinman, which is required for visceral muscle and heart development. D-mef2 expression precedes that of the MyoD homologue, nautilus, and, in contrast to nautilus, D-mef2 appears to be expressed in all somatic and visceral muscle cell precursors. Its temporal and spatial expression patterns suggest that D-mef2 may play an important role in commitment of mesoderm to myogenic lineages.
