Involved in the negative control of telomere length and in telomeric silencing through a replication-mediated pathway. May have a role in Okazaki fragment maturation. Required for S-phase progression. An RFC-like complex (elg1-RFC) is formed where elg1 replaces rfc1 in the RFC complex. This complex appears to have a role in DNA replication, replication fork re-start, recombination and repair. Heteropentamer of elg1, rfc2, rfc3, rfc4 and rfc5 forming the elg1-RFC complex. Belongs to the ELG1 family.
