background:
This gene encodes a protein that functions as part of a heterodimer to activate transcription. The encoded protein forms a heterodimer with Max-like protein X (MLX) and is involved in the regulation of genes in response to cellular glucose levels. [provided by RefSeq, Mar 2014]
Function:
Binds DNA as a heterodimer with MLX and activates transcription. Binds to the canonical E box sequence 5'-CACGTG-3'. Plays a role in transcriptional activation of glycolytic target genes. Involved in glucose-responsive gene regulation.
Subunit:
Efficient DNA binding requires dimerization with another bHLH protein. Binds DNA as a homodimer or a heterodimer with MLX.
Subcellular Location:
Cytoplasm. Nucleus. Mitochondrion outer membrane.
Tissue Specificity:
Widely expressed in adult tissues. Most abundant in skeletal muscle. Ref.1
Similarity:
Contains 1 bHLH (basic helix-loop-helix) domain.
