== Function Summary ==
* **Entrez Summary**: N/A
* **UniProt Summary**: Required for DNA replication. Plays a role in the rescue of stalled replication forks and checkpoint control. Binds double- stranded DNA breaks and nicks as well as single-stranded DNA. Recruits the SWI/SNF chromatin remodeling complex to E2F1- responsive promoters. Down-regulates E2F1 activity and inhibits E2F1-dependent apoptosis during G1/S transition and after DNA damage. Induces a large increase in the kinase activity of ATR (PubMed:16530042). {ECO:0000269|PubMed:10498869, ECO:0000269|PubMed:11395493, ECO:0000269|PubMed:11714696, ECO:0000269|PubMed:12697828, ECO:0000269|PubMed:15075294, ECO:0000269|PubMed:16530042}.
