DNA polymerase eta ( 713 aa, 78 kDa) is specifically involved in DNA repair. Plays an important
role in translesion synthesis, where the normal high fidelity DNA polymerases cannot proceed and DNA
synthesis stalls. Plays an important role in the repair of UV-induced pyrimidine dimers. Depending on the
context, it inserts the correct base, but causes frequent base transitions and transversions. May play a role in
hypermutation at immunoglobulin genes. Forms a Schiff base with 5'-deoxyribose phosphate at abasic sites,
but does not have lyase activity. Targets POLI (Pol iota) to replication foci.
Human recombinant full-size Pol eta tagged with His6.
Western blot. Not tested for other application
Human Pol eta protein. Not tested in other species

Positive control. Lnae 2; Whole cell extract of HeLa cells. ~40 ug protein applied. Positive control Lane 3; Whole cell extract of XP2SA (XP-V) cells. ~40 ug protein applied. Negative control PoL eta is detected at ~80 kDa position. 8% gel was used. Data by courtesy of Prof. F. Hanaoka and Prof. C. Masutani at Osaka University.
