Transcriptional regulator that binds to the upstream enhancer region (CCAC box) of myoglobin gene. Has a role in myogenic differentiation and in remodeling processes of adult muscles that occur in response to physiological stimuli. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
Protein type: Transcription factor; DNA binding protein
Cellular Component: nucleolus; nucleus
Molecular Function: protein binding; sequence-specific DNA binding; transcription factor activity
Biological Process: regulation of transcription from RNA polymerase II promoter; muscle development; transcription, DNA-dependent; positive regulation of transcription, DNA-dependent; negative regulation of cell growth; cell differentiation; negative regulation of transcription, DNA-dependent
SS: The number of records in which this modification site was determined using site-specific methods. SS methods include amino acid sequencing, site-directed mutagenesis, modification site-specific antibodies, specific MS strategies, etc.
