		+	== Function ==
		+	[https://www.uniprot.org/uniprot/DPO4_CALS4 DPO4_CALS4] 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, in conjunction with the beta clamp from PolIII.

		+	== Publication Abstract from PubMed ==
		+	Translesion synthesis (TLS) is a kind of DNA repair that maintains the stability of the genome and ensures the normal growth of life in cells under emergencies. Y-family DNA polymerases, as a kind of error-prone DNA polymerase, mainly perform TLS. Previous studies have suggested that the occurrence of tumors is associated with the overexpression of human DNA polymerase of the Y family. And the combination of Y-family DNA polymerase inhibitors is promising for cancer therapy. Here we report the functional and structural characterization of a member of the Y-family DNA polymerases, TTEDbh. We determine TTEDbh is an extreme TLS polymerase that can cross oxidative damage sites, and further identify the amino acids and novel structures that are critical for DNA binding, synthesis, fidelity, and oxidative damage bypass. Moreover, previously unnoticed structural elements with important functions have been discovered and analyzed. These studies provide a more experimental basis for further elucidating the molecular mechanisms of DNA polymerase in the Y family. It could also shed light on the design of drugs to target tumors.
