Region-specific regulation of the actin multi-gene family in early amphibian embryos.
The actin multi-gene family shows both spatial and temporal regulation during early embryogenesis in the amphibian Xenopus laevis. Both muscle-specific and ubiquitous cytoskeletal actin genes are activated at the end of gastrulation; transcription of the alpha-cardiac and alpha-skeletal actin genes is restricted to the somitic mesoderm and its muscle-forming derivatives providing a convenient molecular marker for this early embryonic tissue.
