STRING protein interaction network
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 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
protein homology

Gene Fusion
kuKu domain-containing protein; With LigD forms a non-homologous end joining (NHEJ) DNA repair enzyme, which repairs dsDNA breaks with reduced fidelity. Stimulates rNTP addition to DSB and end joining (ligation) of linear DNA by LigD, on 3'-overhangs and probably also 5'-overhangs and blunt dsDNA breaks. Binds both ends of linear dsDNA protecting it from exonuclease activity (293 aa)    
Predicted Functional Partners:
Bifunctional non-homologous end joining protein ligd; With Ku probably forms a non-homologous end joining (NHEJ) repair enzyme, which repairs dsDNA breaks (DSB) with reduced fidelity. Acts as a DNA ligase on singly nicked dsDNA, fills dsDNA gaps (3- or 4- nucleotide gaps, prefers a 5'-phosphate at the gap distal end, prefers dNTPs over rNTPs) , has DNA-directed DNA polymerase activity (templated primer extension) and DNA-directed RNA polymerase activity , adds 1 or 2 non-templated rNTP (or less well dNTP) to ssDNA or blunt-end dsDNA (primer extension). Has 3' resection activity, removi [...]
Phosphoesterase; yfcE: phosphodiesterase, MJ0936 family protein
Dna repair protein sbcc/rad50; SbcCD cleaves DNA hairpin structures. These structures can inhibit DNA replication and are intermediates in certain DNA recombination reactions. The complex acts as a 3'->5' double strand exonuclease that can open hairpins. It also has a 5' single-strand endonuclease activity (By similarity)

Putative two-component sensor; Member of the two-component regulatory system PprA/PprB involved in biofilm formation by controlling the expression of many related genes including type IVb pili major subunit flp pilin, adhesin bapA or cupE fimbriae Modulates also quorum-sensing signal production acting on both negative and positive modulators . Functions as a heme sensor histidine kinase which is autophosphorylated at a histidine residue and transfers its phosphate group to PprB
Hypothetical protein; Uncharacterized protein
