STRINGSTRING
STRING protein interaction network
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:
a 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 to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

nei1Possible DNA glycosylase; Involved in base excision repair of DNA damaged by oxidation or by mutagenic agents. DNA glycosylase that recognizes and removes damaged pyrimidines. Excises Tg:A (thymine glycol, prefers 5R isomers), Tg:G, 5,6-dihydrouracil:G base pairs and urea:A, also excises oxidized purine derivatives guanidinohydantoin:C and spiroiminodihydantoin:C. Poorly cleaves dsDNA with uracil substitutions, thus also acting as a weak uracil-DNA glycosylase. Acts on DNA bubble and 3'-fork structures, suggesting a role in replication-associated DNA repair. Activity on 7,8-dihydro-8-o [...] (268 aa)    
Predicted Functional Partners:
nei
Probable endonuclease VIII Nei; Involved in base excision repair of DNA damaged by oxidation or by mutagenic agents. Acts as DNA glycosylase that recognizes and removes damaged bases. Has AP (apurinic/apyrimidinic) lyase activity and introduces nicks in the DNA strand. Cleaves the DNA backbone by beta-delta elimination to generate a single-strand break at the site of the removed base with both 3'- and 5'-phosphates (By similarity). Complements an E.coli nei nth double mutant.

nth
Endonuclease III; DNA repair enzyme that has both DNA N-glycosylase activity and AP-lyase activity. The DNA N-glycosylase activity releases various damaged pyrimidines from DNA by cleaving the N-glycosidic bond, leaving an AP (apurinic/apyrimidinic) site. The AP-lyase activity cleaves the phosphodiester bond 3' to the AP site by a beta-elimination, leaving a 3'-terminal unsaturated sugar and a product with a terminal 5'- phosphate. Has a preference for oxidized pyrimidines, such as thymine glycol (prefers 5S isomers) 5,6-dihydrouracil:G, 5-hydroxyuracil:G, 5- hydroxycytosine:G and urea [...]
