"LIG1" - ligase I, DNA, ATP-dependent in Homo sapiens
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 Size
small protein node
small nodes:
protein of unknown 3D structure
large protein node
large nodes:
some 3D structure is known or predicted
Node Color
colored protein node
colored nodes:
query proteins and first shell of interactors
non-colored protein node
white nodes:
second shell of interactors
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 each other.
Known Interactions
database edge
from curated databases
experiment edge
experimentally determined
Predicted Interactions
neighborhood edge
gene neighborhood
fusion edge
gene fusions
cooccurrence edge
gene co-occurrence
Others
textmining edge
textmining
coexpression edge
co-expression
homology edge
protein homology

LIG1ligase I, DNA, ATP-dependent; DNA ligase that seals nicks in double-stranded DNA during DNA replication, DNA recombination and DNA repair (919 aa)    
Predicted Functional Partners:
PCNA
proliferating cell nuclear antigen; Auxiliary protein of DNA polymerase delta and is involved in the control of eukaryotic DNA replication by increasing the polymerase’s processibility during elongation of the leading strand. Induces a robust stimulatory effect on the 3’- 5’ exonuclease and 3’-phosphodiesterase, but not apurinic- apyrimidinic (AP) endonuclease, APEX2 activities. Has to be loaded onto DNA in order to be able to stimulate APEX2. Plays a key role in DNA damage response (DDR) by being conveniently positioned at the replication fork to coordinate DNA replication with DNA re [...] (261 aa)

CHEK1
checkpoint kinase 1; Serine/threonine-protein kinase which is required for checkpoint-mediated cell cycle arrest and activation of DNA repair in response to the presence of DNA damage or unreplicated DNA. May also negatively regulate cell cycle progression during unperturbed cell cycles. This regulation is achieved by a number of mechanisms that together help to preserve the integrity of the genome. Recognizes the substrate consensus sequence [R-X-X-S/T]. Binds to and phosphorylates CDC25A, CDC25B and CDC25C. Phosphorylation of CDC25A at ’Ser-178’ and ’Thr-507’ and phosphorylation of C [...] (476 aa)

FEN1
flap structure-specific endonuclease 1; Structure-specific nuclease with 5’-flap endonuclease and 5’-3’ exonuclease activities involved in DNA replication and repair. During DNA replication, cleaves the 5’-overhanging flap structure that is generated by displacement synthesis when DNA polymerase encounters the 5’-end of a downstream Okazaki fragment. It enters the flap from the 5’-end and then tracks to cleave the flap base, leaving a nick for ligation. Also involved in the long patch base excision repair (LP-BER) pathway, by cleaving within the apurinic/apyrimidinic (AP) site-terminat [...] (380 aa)

APEX1
APEX nuclease (multifunctional DNA repair enzyme) 1; Multifunctional protein that plays a central role in the cellular response to oxidative stress. The two major activities of APEX1 in DNA repair and redox regulation of transcriptional factors. Functions as a apurinic/apyrimidinic (AP) endodeoxyribonuclease in the DNA base excision repair (BER) pathway of DNA lesions induced by oxidative and alkylating agents. Initiates repair of AP sites in DNA by catalyzing hydrolytic incision of the phosphodiester backbone immediately adjacent to the damage, generating a single-strand break with 5’ [...] (318 aa)

CDK2
cyclin-dependent kinase 2; Serine/threonine-protein kinase involved in the control of the cell cycle; essential for meiosis, but dispensable for mitosis. Phosphorylates CTNNB1, USP37, p53/TP53, NPM1, CDK7, RB1, BRCA2, MYC, NPAT, EZH2. Interacts with cyclins A, B1, B3, D, or E. Triggers duplication of centrosomes and DNA. Acts at the G1-S transition to promote the E2F transcriptional program and the initiation of DNA synthesis, and modulates G2 progression; controls the timing of entry into mitosis/meiosis by controlling the subsequent activation of cyclin B/CDK1 by phosphorylation, and [...] (298 aa)

POLD1
polymerase (DNA directed), delta 1, catalytic subunit; Possesses two enzymatic activities- DNA synthesis (polymerase) and an exonucleolytic activity that degrades single stranded DNA in the 3’- to 5’-direction. Required with its accessory proteins (proliferating cell nuclear antigen (PCNA) and replication factor C (RFC) or activator 1) for leading strand synthesis. Also involved in completing Okazaki fragments initiated by the DNA polymerase alpha/primase complex (1107 aa)
