Genes affected

MYOG (HGNC:7612): (myogenin) Myogenin is a muscle-specific transcription factor that can induce myogenesis in a variety of cell types in tissue culture. It is a member of a large family of proteins related by sequence homology, the helix-loop-helix (HLH) proteins. It is essential for the development of functional skeletal muscle.

MYOG links:

MYOPARR (HGNC:54178): (myogenin promoter associated myogenic regulatory antisense long non coding RNA) Predicted to enable RNA polymerase II core promoter sequence-specific DNA binding activity. Predicted to be involved in myoblast fate specification. Predicted to act upstream of or within with a positive effect on gene expression. Predicted to act upstream of or within protein-containing complex assembly and skeletal muscle fiber development. [provided by Alliance of Genome Resources, Apr 2022]
