proliferating cell nuclear antigen (PCNA) unloading activity of Elg1 is important for coordinating DNA replication forks with the process of replication-coupled nucleosome assembly to maintain silencing of HML and HMR through S-phase
Title: Pivotal roles of PCNA loading and unloading in heterochromatin function.
Identification of new interacting partners and modulators of Mus81-Mms4 nuclease, RFC, and PCNA imply the cooperation of these factors in resolution of stalled replication forks and branched DNA structures emanating from the restarted replication forks under conditions of replication stress.
Title: Role of PCNA and RFC in promoting Mus81-complex activity.
found evidence implicating PCNA in the maintenance of the high-order structure and stability of heterochromatin, which indicates a role of DNA replication in heterochromatin maintenance
Title: Proliferating cell nuclear antigen (PCNA) contributes to the high-order structure and stability of heterochromatin in Saccharomyces cerevisiae.
Eco1 mediated acetylation regulates PCNA sliding on DNA in the presence of DNA damage, favoring homologous recombination linked to sister-chromatid cohesion.
Title: Acetylation of PCNA Sliding Surface by Eco1 Promotes Genome Stability through Homologous Recombination.
Srs2 interaction with PCNA allows the helicase activity to unwind fork-blocking CAG/CTG hairpin structures to prevent DNA breaks during DNA replication. Independently of PCNA binding, Srs2 also displaces Rad51 from nascent strands to prevent recombination-dependent repeat expansions and contractions.
Title: Differential requirement of Srs2 helicase and Rad51 displacement activities in replication of hairpin-forming CAG/CTG repeats.
the various roles of Elg1 in genome stability maintenance involve the unloading of both modified and unmodified PCNA.

results suggest that Elg1-RLC acts as a general PCNA unloader and is dependent upon DNA ligation during chromosome replication.
Title: Replication-Coupled PCNA Unloading by the Elg1 Complex Occurs Genome-wide and Requires Okazaki Fragment Ligation.
Elevated levels of PCNA rescue pds5-1 temperature sensitivity and cohesion defects, but do not rescue pds5-1 mutant cell condensation defects.
