Question: List the components of a Replisome Progression Complex (RPC).

Context:
This interaction requires the RPC components Mrc1 and Ctf4, both of which associate with a tetratricopeptide repeat (TPR) domain located at the amino terminus of Dia2
Here we show that SCF(Dia2) associates with the replisome progression complex (RPC) that assembles around the MCM2-7 helicase at DNA replication forks
We found previously that many regulatory proteins assemble around the MCM2-7 helicase at yeast replication forks to form the replisome progression complex (RPC), which might link MCM2-7 to other replisome components
Here, we show that the RPC associates with DNA polymerase alpha that primes each Okazaki fragment during lagging strand synthesis. Our data indicate that a complex of the GINS and Ctf4 components of the RPC is crucial to couple MCM2-7 to DNA polymerase alpha
Others have found recently that the Mrc1 subunit of RPCs binds DNA polymerase epsilon, which synthesises the leading strand at DNA replication forks
we show that the GINS (go ichi ni san) complex allows the MCM (minichromosome maintenance) helicase to interact with key regulatory proteins in large replisome progression complexes (RPCs) that are assembled during initiation and disassembled at the end of S phase
RPC components include the essential initiation and elongation factor, Cdc45, the checkpoint mediator Mrc1, the Tof1-Csm3 complex that allows replication forks to pause at protein-DNA barriers, the histone chaperone FACT (facilitates chromatin transcription) and Ctf4, which helps to establish sister chromatid cohesion. RPCs also interact with Mcm10 and topoisomerase I
During initiation, GINS is essential for a specific subset of RPC proteins to interact with MCM. GINS is also important for the normal progression of DNA replication forks, and we show that it is required after initiation to maintain the association between MCM and Cdc45 within RPCs
We found previously that many regulatory proteins assemble around the MCM2-7 helicase at yeast replication forks to form the replisome progression complex (RPC), which might link MCM2-7 to other replisome components.
Here we show that SCF(Dia2) associates with the replisome progression complex (RPC) that assembles around the MCM2-7 helicase at DNA replication forks [6].
Compared with wild type, hydroxyurea-treated ctf18жд cells exhibited increased chromatin association of replisome progression complex components including Cdc45, Ctf4, and GINS complex subunits, the polymerase processivity clamp PCNA and the single-stranded DNA-binding complex RPA.
The amino-terminal TPR domain of Dia2 tethers SCF(Dia2) to the replisome progression complex.
Ctf4 is a protein conserved in eukaryotes and a constituent of the replisome progression complex.
Eukaryotic GINS also links with other key proteins at the fork to maintain an active replisome progression complex.
Dia2 has previously been implicated in the control of replication and genome stability via its interaction with the replisome progression complex.
The Cdc45-MCM-GINS complex could constitute the core of a larger macromolecular structure that has been termed the "replisome progression complex".
FACT does not associate with the Mcm2-7 helicase at replication origins during G1 phase but is subsequently incorporated into the replisome progression complex independently of histone binding and uniquely among histone chaperones.
Our data indicate that a complex of the GINS and Ctf4 components of the RPC is crucial to couple MCM2-7 to DNA polymerase alpha.
Replisome progression complex links DNA replication to sister chromatid cohesion in Xenopus egg extracts.
On the basis of the physical interactions between AND-1 and DNA polymerases, we discuss a model to describe how replisome progression complex establishes sister chromatid cohesion.
The components of the replisome that preserve genomic stability by controlling the progression of eukaryotic DNA replication forks are poorly understood.
RPC components include the essential initiation and elongation factor, Cdc45, the checkpoint mediator Mrc1, the Tof1-Csm3 complex that allows replication forks to pause at protein-DNA barriers, the histone chaperone FACT (facilitates chromatin transcription) and Ctf4, which helps to establish sister chromatid cohesion.

Answer: RPC components include the essential initiation and elongation factor, Cdc45, the checkpoint mediator Mrc1, the Tof1-Csm3 complex that allows replication forks to pause at protein-DNA barriers, the histone chaperone FACT (facilitates chromatin transcription) and Ctf4, which helps to establish sister chromatid cohesion. RPCs also interact with Mcm10 and topoisomerase I.

Here, we show that the RPC associates with DNA polymerase alpha that primes each Okazaki fragment during lagging strand synthesis. During initiation, GINS is essential for a specific subset of RPC proteins to interact with MCM. GINS is also important for the normal progression of DNA replication forks, and we show that it is required after initiation to maintain the association between MCM and Cdc45 within RPCs.
