SignalDependentRegulationofMyogenesisbyCorepressorMITR
The differentiation of muscle cells is regulated by many factors, including the MyoD/MEF2 family of transcription factors. The MyoD/MEF2 dimer binds to promoters to activate genes involved in muscle cell differentiation. One of the factors that regulates the role of MyoD/MEF2 in myogenesis is the protein MEF2-interacting transcription repressor (MITR), a transcriptional repressor. When MITR is bound to MEF2, myogenes......阅读全文
