CTF4

CHL15, POB1, chromatin-binding protein CTF4, L000000326, YPR135W
Chromatin-associated protein; required for sister chromatid cohesion; interacts with DNA polymerase alpha (Pol1p) and may link DNA synthesis to sister chromatid cohesion
Saccharomyces cerevisiae (S288c)
PREY

POL2

DUN2, DNA polymerase epsilon catalytic subunit, L000001461, YNL262W
Catalytic subunit of DNA polymerase (II) epsilon; a chromosomal DNA replication polymerase that exhibits processivity and proofreading exonuclease activity; participates in leading-strand synthesis during DNA replication; also involved in DNA synthesis during DNA repair; interacts extensively with Mrc1p
Saccharomyces cerevisiae (S288c)

Synthetic Lethality

A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.

Publication

Ctf18-RFC and DNA Pol ? form a stable leading strand polymerase/clamp loader complex required for normal and perturbed DNA replication.

Stokes K, Winczura A, Song B, Piccoli G, Grabarczyk DB

The eukaryotic replisome must faithfully replicate DNA and cope with replication fork blocks and stalling, while simultaneously promoting sister chromatid cohesion. Ctf18-RFC is an alternative PCNA loader that links all these processes together by an unknown mechanism. Here, we use integrative structural biology combined with yeast genetics and biochemistry to highlight the specific functions that Ctf18-RFC plays within the leading ... [more]
