Mechanisms underlying the transcriptional regulation of skeletal myogenesis.

During skeletal myogenesis, chromatin-modifying enzymes are engaged at discrete genomic regions by transcription factors that recognize sequence-specific DNA motifs located at muscle gene regulatory regions. The composition of the chromatin-bound protein complexes and their temporally and spatially regulated recruitment influence gene expression. Recent findings are consistent with the concept that chromatin modifiers play an important role in regulating skeletal muscle gene expression and cellular differentiation.
