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

neiProbable 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. (255 aa)

rnc
Probable ribonuclease III Rnc (RNase III); Digests double-stranded RNA. Involved in the processing of primary rRNA transcript to yield the immediate precursors to the large and small rRNAs (23S and 16S). Processes some mRNAs, and tRNAs when they are encoded in the rRNA operon. Processes pre-crRNA and tracrRNA of type II CRISPR loci if present in the organism (By similarity). Belongs to the ribonuclease III family.

nei1
Possible 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 [...]

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 [...]

recA
RecA protein (recombinase A) [contains: endonuclease PI-MTUI (MTU RecA intein)]; Can catalyze the hydrolysis of ATP in the presence of single- stranded DNA, the ATP-dependent uptake of single-stranded DNA by duplex DNA, and the ATP-dependent hybridization of homologous single-stranded DNAs. It interacts with LexA causing its activation and leading to its autocatalytic cleavage.
