Instead, this is carried out by an extender polymerase (PolTLSext), most commonly Pol ζ, which can deal with the highly misaligned terminus. Pol ζ has been notoriously hard to study in vertebrate cells.

Further, genetic analysis in DT40 cells suggests that Pol ζ contributes to the extension of at least some bypass events in the Ig locus (Hirota et al. 2010). For example, the E3 ligase responsible for PCNA polyubiquitination is also required for efficient TLS in both S.

In vivo, however, Pol η-deficient cells do not exhibit a significant defect in the replication of (6-4) photoproducts, suggesting that other polymerases, possibly Pol ζ, are normally responsible for accurate replication

Environ. Pol η-deficient cells are hypermutable following UV exposure (Stary et al. 2003; Choi and Pfeifer 2005; Busuttil et al. 2008), which results from inaccurate bypass of CPDs by Pol κ or The DNA is in black, and the active site in the palm and incoming nucleotide triphosphate is in red.

Rhombic-faced polyhedron crystals were obtained using the sitting drop vapor diffusion method at 4 °C in drops containing 1.6 μl of the quaternary protein complex and 0.7 μl of well solution S. The role of the amino-terminal BRCT domain of REV1 remains incompletely understood.

D. In particular, side chains of Leu-186 and Pro-188, located on the front side of the β8′ strand of Rev7, project from the central β-sheet and wedge into a deep and narrow

These results suggest that Spartan negatively regulates POLD3 function in Rev1/Pol ζ-dependent TLS, revealing a previously unrecognized regulatory step in error-prone TLS. There is strong evidence that the deoxycytidyl transferase activity of REV1 contributes to generating C to G transversion mutations (Jansen et al. 2006; Ross and Sale 2006; Masuda et al. 2009), Previous SectionNext Section THE ROLE OF TRANSLESION SYNTHESIS IN SOMATIC MUTATION OF IMMUNOGLOBULIN GENES During the vertebrate immune response, TLS is co-opted to help generate an extraordinarily high level of mutagenesis The therapeutic efficacy of NPs containing both cisplatin prodrug and REV1/REV3L-specific siRNAs was further investigated in vitro and in vivo.
