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

Score
ligC2DNA ligase; DNA ligase that seals nicks in double-stranded DNA during DNA replication, DNA recombination and DNA repair (By similarity). Has weak intrinsic nick joining activities and accumulates DNA-adenylate. Acts as a backup for LigD in the Ku-LigD-dependent NHEJ pathway. (354 aa)    
Predicted Functional Partners:
ligD
DNA polymerase LigD, polymerase domain; Identified by match to protein family HMM TIGR02778.

ku
Ku protein; With LigD forms a non-homologous end joining (NHEJ) repair enzyme which repairs blunt-end and 5'-overhang double strand breaks (DSB) with about 50% fidelity, and DSB with non-complementary 3' ends. Plays a partial role in NHEJ on 3'-overhang repair of complementary ends. NHEJ repairs DSB with blunt ends and 5' overhangs with a high level of nucleotide insertion/deletion, without a need for microhomology. This protein but not LigD also suppresses homologous recombination. Overexpression dramatically increases the efficiency of NHEJ with no effect on repair fidelity.

Conserved hypothetical protein.

polA
DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity; Belongs to the DNA polymerase type-A family.
  
 0.927
dnaN
DNA polymerase III, beta subunit; Confers DNA tethering and processivity to DNA polymerases and other proteins. Acts as a clamp, forming a ring around DNA (a reaction catalyzed by the clamp-loading complex) which diffuses in an ATP- independent manner freely and bidirectionally along dsDNA. Initially characterized for its ability to contact the catalytic subunit of DNA polymerase III (Pol III), a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria; Pol III exhibits 3'-5' exonuclease proofreading activity. The beta chain is required for initiation of [...]

ligA
DNA ligase, NAD-dependent; DNA ligase that catalyzes the formation of phosphodiester linkages between 5'-phosphoryl and 3'-hydroxyl groups in double- stranded DNA using NAD as a coenzyme and as the energy source for the reaction. It is essential for DNA replication and repair of damaged DNA (Probable). Probably the only ligase required for non-homologous end joining (NHEJ) repair of 3-overhangs; Belongs to the NAD-dependent DNA ligase family. LigA subfamily.
