Replication initiator 1 (REPIN1)

Sequence-specific double-stranded DNA-binding protein required for initiation of chromosomal DNA replication. Binds on 5'-ATT-3' reiterated sequences downstream of the origin of bidirectional replication (OBR) and a second, homologous ATT series of reverse orientation situated within the OBR zone.

Facilitates DNA bending. .
