POL1

CDC17, CRT5, HPR3, DNA-directed DNA polymerase alpha catalytic subunit POL1, L000000257, YNL102W
Catalytic subunit of the DNA polymerase I alpha-primase complex; required for the initiation of DNA replication during mitotic DNA synthesis and premeiotic DNA synthesis
Saccharomyces cerevisiae (S288c)
PREY

MEC1

ESR1, RAD31, SAD3, protein kinase MEC1, L000000586, S000029404, S000007656, YBR136W
Genome integrity checkpoint protein and PI kinase superfamily member; Mec1p and Dun1p function in same pathway to regulate dNTP pools and telomere length; signal transducer required for cell cycle arrest and transcriptional responses to damaged or unreplicated DNA; facilitates replication fork progression and regulates P-body formation under replication stress; promotes interhomolog recombination by phosphorylating Hop1p; associates with shortened, dysfunctional telomeres
Saccharomyces cerevisiae (S288c)

Synthetic Growth Defect

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

Separable, Ctf4-mediated recruitment of DNA Polymerase ? for initiation of DNA synthesis at replication origins and lagging-strand priming during replication elongation.

Porcella SY, Koussa NC, Tang CP, Kramer DN, Srivastava P, Smith DJ

During eukaryotic DNA replication, DNA polymerase alpha/primase (Pol ?) initiates synthesis on both the leading and lagging strands. It is unknown whether leading- and lagging-strand priming are mechanistically identical, and whether Pol ? associates processively or distributively with the replisome. Here, we titrate cellular levels of Pol ? in S. cerevisiae and analyze Okazaki fragments to study both replication initiation ... [more]
