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

l(2)dtlProtein lethal(2)denticleless; Substrate-specific adapter of a DCX (DDB1-CUL4-X-box) E3 ubiquitin-protein ligase complex required for cell cycle control. The DCX(DTL) complex, also named CRL4(CDT2) complex, mediates the polyubiquitination and subsequent degradation of E2f during S phase. E2f degradation is necessary to ensure proper development. Substrates require their interaction with PCNA for their polyubiquitination: substrates interact with PCNA via their PIP-box, leading to recruit the DCX(DTL) complex; Belongs to the WD repeat cdt2 family. (769 aa)    
Predicted Functional Partners:
pic
Piccolo (pic) encodes the Ddb1 protein, which functions to recruit substrate receptors to Cul4-based E3 ubiquitin ligase complexes, which catalyze the ubiquitylation and subsequent destruction of proteins that function in cell growth and proliferation as well as transcription, replication and repair of the genome.
   
 0.997
Cul4
Cullin 4 (Cul4) encodes the molecular scaffold for the CRL4 E3 ubiquitin ligase complex, which catalyzes the ubiquitylation and subsequent destruction of proteins that function in cell growth and proliferation as well as transcription, replication and repair of the genome; Belongs to the cullin family.
   
 0.995
dup
Double parked (dup) encodes an essential protein for the initiation of DNA replication due to its recruitment of the MCM helicase to replication origins.
   
 
 0.980
Cdc6
Cell division control protein; Cdc6 (Cdc6) encodes an essential component of the pre-Replication complex (preRC) together with the origin recognition complex, the product of dup and MCM2-7 proteins. The preRC is present at all chromosomal origins of replication and is required for the initiation of DNA replication. The product of Cdc6 also functions in the co-ordination of DNA replication with mitosis, and may contribute to apoptosis and transcription; Belongs to the CDC6/cdc18 family.
   
  
 0.961
Ctf4
Chromosome transmission fidelity 4; Chromatin binding.
   
  
 0.961
PCNA
Proliferating cell nuclear antigen; Likely to be an auxiliary protein of DNA polymerase delta complex and is probably involved in the control of DNA replication and repair by increasing the polymerase's processibility. Belongs to the PCNA family.
   
 0.955
Cdc45
CDC45L (CDC45L) encodes a protein that contributes to 3'-5' DNA helicase activity of the Cdc45/Mcm2-7/GINS complex. It is involved in chromosome condensation and the regulation of the mitotic G1/S transition.
   
  
 0.937
Mcm10
Protein MCM10 homolog; Proposed to be involved in DNA replication and to participate in the activation of the pre-replication complex (pre-RC). May be involved in chromosome condensation.
   
  
 0.912
DNApol-alpha60
DNA primase large subunit; Regulatory subunit of the DNA primase complex and component of the DNA polymerase alpha complex (also known as the alpha DNA polymerase-primase complex) which play an essential role in the initiation of DNA synthesis. During the S phase of the cell cycle, the DNA polymerase alpha complex (composed of a catalytic subunit DNApol- alpha180/DNApolA1, an accessory subunit DNApol-alpha73/DNApolA2 and two primase subunits, the catalytic subunit DNApol-alpha50/DNAprim1 and the regulatory subunit DNApol-alpha60/DNAprim2) is recruited to DNA at the replicative forks (B [...]

tos
Exonuclease 1; 5'->3' double-stranded DNA exonuclease which may also contain a cryptic 3'->5' double-stranded DNA exonuclease activity. Also exhibits endonuclease activity against 5'-overhanging flap structures similar to those generated by displacement synthesis when DNA polymerase encounters the 5'-end of a downstream Okazaki fragment. Required for DNA mismatch repair (MMR) (By similarity).
