part of replication fork protection complex https://github.com/geneontology/go-ontology/issues/29498 TIMELESS-TIPIN complex FPC Swi1-Swi3 complex GO:0031298 cellular_component A heterotrimeric replication-pausing complex conserved in eukaryotes and associated with the replication fork; the complex stabilizes stalled replication forks and is thought to be involved in coordinating leading- and lagging-strand synthesis and in replication checkpoint signaling. Required for maximal fork speed both in vivo and in vitro. fork pausing complex nuclear replication fork nuclear protein-containing complex
