STRINGSTRING
APN2 protein (Saccharomyces cerevisiae) - STRING interaction network
"APN2" - Class II abasic in Saccharomyces cerevisiae
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
some 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

APN2Class II abasic (AP) endonuclease involved in repair of DNA damage; homolog of human HAP1 and E. coli exoIII; DNA repair enzyme that cleaves apurinic/apyrimidinic (AP) sites and removes 3’-blocking groups present at single strand breaks of damaged DNA (520 aa)    
Predicted Functional Partners:
NTG2
DNA N-glycosylase and apurinic/apyrimidinic (AP) lyase involved in base excision repair, localizes to the nucleus; sumoylated; Bifunctional DNA N-glycosylase with associated apurinic/apyrimidinic (AP) lyase function that catalyzes the first step in base excision repair (BER), the primary repair pathway for the repair of oxidative DNA damage. The DNA N-glycosylase activity releases the damaged DNA base from DNA by cleaving the N- glycosidic bond, leaving an AP site. The AP-lyase activity cleaves the phosphodiester bond 3’ to the AP site by a beta-elimination. Primarily recognizes and re [...] (380 aa)

POL30
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; This protein is an auxiliary protein of DNA polymerase delta and is involved in the control of eukaryotic DNA replication by increasing the polymerase’s processibility during elongation of the leading strand. Involved in DNA repair (258 aa)

NTG1
DNA N-glycosylase and apurinic/apyrimidinic (AP) lyase involved in base excision repair; acts in both nucleus and mitochondrion; creates a double-strand break at mtDNA origins that stimulates replication in response to oxidative stress; Bifunctional DNA N-glycosylase with associated apurinic/apyrimidinic (AP) lyase function that catalyzes the first step in base excision repair (BER), the primary repair pathway for the repair of oxidative DNA damage. The DNA N-glycosylase activity releases the damaged DNA base from DNA by cleaving the N- glycosidic bond, leaving an AP site. The AP-lyase [...] (399 aa)

APN1
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; DNA repair enzyme that cleaves apurinic/apyrimidinic (AP) sites and removes 3’-blocking groups present at single strand breaks of damaged DNA. APN1 accounts for > 97% of both apurinic/ apyrimidinic (AP) lyase and DNA 3’-repair diesterase activities (367 aa)

RAD27
5’ to 3’ exonuclease, 5’ flap endonuclease, required for Okazaki fragment processing and maturation as well as for long-patch base-excision repair; member of the S. pombe RAD2/FEN1 family; Structure-specific nuclease with 5’-flap endonuclease and 5’-3’ exonuclease activities involved in DNA replication and repair. During DNA replication, cleaves the 5’-overhanging flap structure that is generated by displacement synthesis when DNA polymerase encounters the 5’-end of a downstream Okazaki fragment. It enters the flap from the 5’-end and then tracks to cleave the flap base, leaving a nick [...] (382 aa)

CDC9
DNA ligase found in the nucleus and mitochondria, an essential enzyme that joins Okazaki fragments during DNA replication; also acts in nucleotide excision repair, base excision repair, and recombination; DNA ligase that seals nicks in double-stranded DNA during DNA replication, DNA recombination and DNA repair. The mitochondrial form is required for mitochondrial DNA maintenance but is non-essential while the nuclear form is essential for cell viability (755 aa)

MAG1
3-methyl-adenine DNA glycosylase involved in protecting DNA against alkylating agents; initiates base excision repair by removing damaged bases to create abasic sites that are subsequently repaired; Hydrolysis of the deoxyribose N-glycosidic bond to excise 3-methyladenine or 7-methyladenine from the damaged DNA polymer formed by alkylation lesions (296 aa)

OGG1
Mitochondrial glycosylase/lyase that specifically excises 7,8-dihydro-8-oxoguanine residues located opposite cytosine or thymine residues in DNA, repairs oxidative damage to mitochondrial DNA, contributes to UVA resistance; DNA repair enzyme that incises DNA at 8-oxoG residues. Excises 7,8-dihydro-8-oxoguanine and 2,6-diamino-4-hydroxy-5-N- methylformamidopyrimidine (FAPY) from damaged DNA. Has a beta- lyase activity that nicks DNA 3’ to the lesion (376 aa)
