Loads PCNA onto primed templates regulating velocity, spacing and restart activity of replication forks. May couple DNA replication to sister chromatid cohesion through regulation of the acetylation of the cohesin subunit SMC3. {ECO:0000269|PubMed:12766176, ECO:0000269|PubMed:19907496}. This is the function of DSCC1 (DNA replication and sister chromatid cohesion 1, Ensembl gene identifier ENSG00000136982).
