BAIT

POL31

HUS2, HYS2, SDP5, L000002981, YJR006W
Subunit of DNA polymerase delta (polymerase III); essential for cell viability; involved in DNA replication and DNA repair; forms a complex with Rev3p, Rev7p and Pol32p; relocalizes to the cytosol in response to hypoxia
Saccharomyces cerevisiae (S288c)
PREY

POL30

proliferating cell nuclear antigen, PCNA, L000001463, YBR088C
Proliferating cell nuclear antigen (PCNA); functions as the sliding clamp for DNA polymerase delta; may function as a docking site for other proteins required for mitotic and meiotic chromosomal DNA replication and for DNA repair
Saccharomyces cerevisiae (S288c)

Two-hybrid

Bait protein expressed as a DNA binding domain (DBD) fusion and prey expressed as a transcriptional activation domain (TAD) fusion and interaction measured by reporter gene activation.

Publication

The inner side of yeast PCNA contributes to genome stability by mediating interactions with Rad18 and the replicative DNA polymerase ?.

Toth R, Halmai M, Gyorfy Z, Balint E, Unk I

PCNA is a central orchestrator of cellular processes linked to DNA metabolism. It is a binding platform for a plethora of proteins and coordinates and regulates the activity of several pathways. The outer side of PCNA comprises most of the known interacting and regulatory surfaces, whereas the residues at the inner side constitute the sliding surface facing the DNA double ... [more]
