Histone H4 transcription factor (HINFP)

Transcriptional repressor that binds to the consensus sequence 5'-CGGACGTT-3' and to the RB1 promoter. Transcriptional activator that promotes histone H4 gene transcription at the G1/S phase transition in combination with NPAT.

Also activates transcription of the ATM and PRKDC genes. Autoregulates its expression by associating with its own promoter.
