title: The M-twist gene of Mus is expressed in subsets of mesodermal cells and is closely related to the Xenopus X-twi and the Drosophila twist genes.
abstract: The twist gene was characterized in Drosophila as being necessary at gastrulation for the establishment of the mesodermal germ layer. It codes for a nuclear DNA-binding protein that is probably a transcription factor. We have cloned and sequenced the M-twist gene of Mus musculus. The deduced proteins encoded by the Mus, Xenopus, and Drosophila twist cDNAs, respectively, show a high degree of similarity. Northern blot analyses and in situ hybridizations reveal that the 1.7-kb murine M-twist m-RNA is present at early stages, starting at 8 days post coitum, and is expressed the most at 9.5 days in the cephalic and branchial mesectoderm, in some derivatives of the mesodermal layer (sclerotoma and somatopleura), and in the limb buds.
