MYOD1（myogenic differentiation 1），癌症关联基因，基因ID：4654，该基因编码一种核蛋白，属于转录因子和肌生成因子亚家族的基本螺旋环螺旋家族。它通过诱导细胞周期停滞来调节肌肉细胞分化，这是肌源性启动的先决条件。这种蛋白质也参与肌肉再生。它激活自身的转录，可能稳定对肌生成的承诺。[由RefSeq提供，2008年7月]This gene encodes a nuclear protein that belongs to the basic helix-loop-helix family of transcription factors and the myogenic factors subfamily. It regulates muscle cell differentiation by inducing cell cycle arrest， a prerequisite for myogenic initiation. The protein is also involved in muscle regeneration. It activates its own transcription which may stabilize commitment to myogenesis. [provided by RefSeq， Jul 2008]。
