Wild-type and chimeric HLF proteins also bound closely related sites identified previously for bZIP proteins of both the proline -and acidic amino acid-rich ( PAR ) and C/EBP subfamilies ; however, E2A- HLF proteins were significantly less tolerant of certain deviations from the HLF consensus binding site .
