In molecular biology the myogenic determination factor 5 proteins are a family of proteins found in eukaryotes. This family includes the Myf5 protein which is responsible for directing cells to the skeletal myocyte lineage during development. Myf5 is likely to act in a similar way to the other MRF4 proteins such as MyoD which perform the same function. These are histone acetyltransferases and histone deacetylases which activate and repress genes involved in the myocyte lineage.
