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

dnl1DNA ligase I, ATP-dependent; DNA ligase that seals nicks in double-stranded DNA during DNA replication, DNA recombination and DNA repair; Belongs to the ATP-dependent DNA ligase family. (509 aa)    
Predicted Functional Partners:
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.

ligD-2
DNA ligase; With Ku forms a non-homologous end joining (NHEJ) repair enzyme which repairs blunt-end and 5'-overhang DNA double strand breaks (DSB) with about 50% fidelity, and DSB with non-complementary 3' ends. Plays a partial role in NHEJ during 3'-overhang repair. NHEJ repairs DSB with blunt ends and 5' overhangs with a high level of nucleotide insertion/deletion, without a need for microhomology. Acts as a DNA ligase on singly nicked dsDNA, as a DNA-directed DNA polymerase on 5' overhangs, and adds non-templated nucleotides to 3' overhangs (terminal transferase). Fills in gaps in d [...]

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 [...]

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.

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.

ligD
DNA polymerase LigD, polymerase domain; Identified by match to protein family HMM TIGR02778.

ABK72031.1
5'-3' exonuclease; Identified by match to protein family HMM PF01367; match to protein family HMM PF02739.

recC
Exodeoxyribonuclease V, gamma subunit; A helicase/nuclease that prepares dsDNA breaks (DSB) for recombinational DNA repair. Binds to DSBs and unwinds DNA via a highly rapid and processive ATP-dependent bidirectional helicase activity. Holoenzyme degrades any linearized DNA that is unable to undergo homologous recombination. In the holoenzyme this subunit recognizes the wild-type Chi sequence, and when added to isolated RecB increases its ATP-dependent helicase processivity (By similarity). Unlike the case in E.coli, suppresses RecA-dependent homologous recombination, is instead require [...]
