== Function ==

[https://www.uniprot.org/uniprot/DPO4_SACSO DPO4_SACSO] Poorly processive, error-prone DNA polymerase involved in untargeted mutagenesis. Copies undamaged DNA at stalled replication forks, which arise in vivo from mismatched or misaligned primer ends. These misaligned primers can be extended by PolIV. Exhibits no 3'-5' exonuclease (proofreading) activity. May be involved in translesional synthesis.

== Publication Abstract from PubMed ==
 +
A new group of error-prone DNA polymerases overcomes the blockage posed to normal DNA replication by damaged template bases, suggesting an active site with a loose, flexible pocket that accommodates aberrant DNA structures. We have determined a 2.8 A resolution crystal structure of the Sulfolobus solfataricus Dbh protein, a DNA translesion polymerase closely related to Escherichia coli DNA polymerase IV and human polymerase kappa. A high error rate is observed for the Dbh polymerase in a range of 10(-2)-10(-3) for all 12 base substitution mispairs. The crystal structure of Dbh reveals an overall architecture resembling other DNA polymerases but has unique features that are likely to contribute to error-prone synthesis, including -1 frameshifting mutations.
