Rad52 and Rad51 most likely facilitate bypassing the blocking lesion and then remain bound to the ssDNA gaps left behind the fork until G2 (Fig. 3).
An important consequence of gene deregulation through RB loss is the propensity to facilitate bypass of the canonical DNA damage checkpoints that inhibit G1 and S-phase progression [15], [16].
The Y-family DNA polymerases represent a specialized class of enzymes that are thought to facilitate bypass of DNA adducts when the replicative polymerases are inhibited (14, 15).
Taken together, our results provide new structural and dynamic insights into how the spacious Polκ gap and flexible N-clasp facilitate bypass of minor groove polycyclic aromatic lesions and show how lesion topology provides structural and dynamic signals that determine the extent of fidelity in bypass by Polκ.
This observance, coupled with the structural similarity of Dna2 to the Upf1 subfamily of RNA/DNA helicases raises the possibility that the helicase activity facilitates the bypassing of the 5' RNA primer of Okazaki fragments.
Conventional grid systems operate satisfactorily provided the network exhibits spare capacity, both in terms of redundant transmission line routes, to facilitate the bypassing of damaged lines, and in terms of power generators to ensure a balance between supply and demand can be maintained in all circumstances.
The glomerular endothelial cells (GEC) are striking in their fenestrated structure, which facilitates fluid bypass to the glomerular basement membrane.
Therefore, we hypothesized that v-CFLAR/v-FLIP facilitates OIS bypass during latent KSHV infection by suppressing autophagy.
For example, PCNA is ubiquitinated by the RING E3 ligase RAD18, a modification that triggers the translesion synthesis pathway, which facilitates the bypass of lesions that block DNA polymerase progression [ 6].
It has been suggested that ring opening of the (6 S -HNE-1 S -HNE-1, N-dGuo facilitateS -HNE-1 bypass by Y-family polymerases, which may account for the low levels of mutations associated with these lesions.
