Replication Termination Factor 2, abbreviated as RTF2, is a protein encoded by the RTF2 gene in humans. This protein plays an integral role in the termination phase of DNA replication. During replication, DNA polymerases duplicate the genome by synthesizing new strands of DNA using the original strands as templates. This process is highly regulated and requires precise coordination to ensure that the entire genome is accurately replicated once and only once during each cell cycle.

RTF2 is implicated in the process that ensures replication forks do not continue replicating DNA beyond the point at which they should stop, which is crucial for maintaining genomic stability. The termination phase occurs when two replication forks, which have been replicating DNA bidirectionally, meet. RTF2 contributes to the cessation of replication fork progression and helps to facilitate the proper disassembly of the replication machinery at the conclusion of DNA synthesis. This action is vital to prevent over-replication or incomplete replication of the DNA, which can lead to mutations or chromosomal rearrangements that are often associated with cancer and other genetic disorders.The protein interacts with other replication factors and components of the replication machinery, suggesting a complex mechanism that signals the end of DNA replication. Although the exact molecular details of RTF2's function are not fully understood, it is believed to act as a scaffold or signaling molecule that brings together various proteins necessary for replication termination.
