Fig. 7From: Relationship between the structure and function of the transcriptional regulator E2AThe interaction within the E2A bHLH dimer. Shaded residues are in the dimer interface: hydrophobic residues are in blue. The residues involved in hydrogen bonding are marked with symbols: ↔, E2A homodimer; *, E2A-class II bHLH heterodimers; ▲, E2A–ID1 heterodimer. Amino acid positions 547–608 of E47 were obtained from UniProtKB (P15923-2)Back to article page
