HHL, HRY, HES-1, bHLHb39, Transcription factor HES-1, Class B basic helix-loop-helix protein 39, Hairy and enhancer of split 1, Hairy homolog, Hairy-like protein, HES1, HL
Transcriptional repressor of genes that require a bHLH protein for their transcription. May act as a negative regulator of myogenesis by inhibiting the functions of MYOD1 and ASH1. Binds DNA on N-box motifs: 5-CACNAG-3 with high affinity and on E-box motifs: 5-CANNTG-3 with low affinity (By similarity). May play a role in a functional FA core complex response to DNA cross-link damage, being required for the stability and nuclear localization of FA core complex proteins, as well as for FANCD2 monoubiquitination in response to DNA damage.
