The simple/helix-loop-helix (bHLH) proteins are a superfamily of transcription factors that bind as dimers to specific DNA target sites and that have been well characterized in nonplant eukaryotes as important regulatory components in diverse biological processes. subfamilies. Considerable diversity in DNA binding site specificity among family members is predicted, and noticeable divergence in protein sequence… Continue reading The simple/helix-loop-helix (bHLH) proteins are a superfamily of transcription factors that
