APN1

DNA-(apurinic or apyrimidinic site) lyase APN1, L000000096, YKL114C
Major apurinic/apyrimidinic endonuclease; 3'-repair diesterase; involved in repair of DNA damage by oxidation and alkylating agents; also functions as a 3'-5' exonuclease to repair 7,8-dihydro-8-oxodeoxyguanosine; genetically interacts with NTG1 to maintain mitochondrial genome integrity
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 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.

Abasic sites linked to dUTP incorporation in DNA are a major cause of spontaneous mutations in absence of base excision repair and Rad17-Mec3-Ddc1 (9-1-1) DNA damage checkpoint clamp in Saccharomyces cerevisiae.

Collura A, Auffret Van Der Kemp P, Boiteux S

In Saccharomyces cerevisiae, inactivation of base excision repair (BER) AP endonucleases (Apn1p and Apn2p) results in constitutive phosphorylation of Rad53p and delay in cell cycle progression at the G2/M transition. These data led us to investigate genetic interactions between Apn1p, Apn2p and DNA damage checkpoint proteins. The results show that mec1 sml1, rad53 sml1 and rad9 is synthetic lethal with ...

Phenotypic Suppression

A genetic interaction is inferred when mutation or over expression of one gene results in suppression of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.
