Splet06. apr. 2024 · Recently, HMCES (5-hydroxymethylcytosine binding, ES cell specific), a replication fork-associated protein (20, 21), was discovered to interact with the aldehyde form of AP sites and generate stable thiazolidine protein-DNA crosslinks (20, 22–24). The crosslinking reaction is specific to AP sites in single-stranded DNA (ssDNA) (20, 22, 23). Splet19. sep. 2024 · Our results suggest that although PCNA is much more competitive than XPA in binding replication forks, PCNA sequestration by progerin may shift the equilibrium to favor XPA binding. Furthermore, we demonstrated that progerin-induced apoptosis could be rescued by XPA, suggesting that XPA-replication fork binding may prevent apoptosis in … princess cookie cutters michaelsSpletPCNA, the Maestro of the Replication Fork George-Lucian Moldovan, Boris Pfander, and Stefan Jentsch Table S1.
