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

Top2DNA topoisomerase 2; Control of topological states of DNA by transient breakage and subsequent rejoining of DNA strands. Topoisomerase II makes double-strand breaks. Essential during mitosis and meiosis for proper segregation of daughter chromosomes. During meiosis, it disrupts heterochromatic connections between achiasmate and chiasmate homologs after spindle assembly so that chromosomes can separate at prometaphase I. During mitosis, it functions in the separation of sister chromatids by establishing amphitelic kinetochore attachments in mitotic spindles. May have a role in chromatin [...] (1447 aa)    
Predicted Functional Partners:
Top1
DNA topoisomerase 1; Releases the supercoiling and torsional tension of DNA introduced during the DNA replication and transcription by transiently cleaving and rejoining one strand of the DNA duplex (By similarity). Introduces a single-strand break via transesterification at a target site in duplex DNA (By similarity). The scissile phosphodiester is attacked by the catalytic tyrosine of the enzyme, resulting in the formation of a DNA-(3'-phosphotyrosyl)-enzyme intermediate and the expulsion of a 5'-OH DNA strand (By similarity). The free DNA strand then undergoes passage around the unb [...]

SMC2
Structural maintenance of chromosomes 2 (SMC2) encodes a condensin subunit involved in chromosome condensation and cell division. It contributes to neurogenesis and stem cell differentiation.
   
 
 0.975
barr
Condensin complex subunit 2; Barren (barr) encodes a chromatin binding protein involved in chromatin condensation. It regulates Malpighian tubule development and epithelial morphogenesis.
   
 
 0.972
glu
Structural maintenance of chromosomes protein; Gluon (glu) encodes a subunit of the multiprotein complex condensin that is required for chromosome condensation and sister chromatid segregation. It contributes to nervous system development and glucose metabolism.
   
 
 0.946
Top3beta
DNA topoisomerase 3-beta; Releases the supercoiling and torsional tension of DNA introduced during the DNA replication and transcription by transiently cleaving and rejoining one strand of the DNA duplex. Introduces a single-strand break via transesterification at a target site in duplex DNA. The scissile phosphodiester is attacked by the catalytic tyrosine of the enzyme, resulting in the formation of a DNA-(5'-phosphotyrosyl)- enzyme intermediate and the expulsion of a 3'-OH DNA strand. The free DNA strand than undergoes passage around the unbroken strand thus removing DNA supercoils. [...]

CG14647
BTB domain-containing protein; It is involved in the biological process described with: protein homooligomerization.
   
 
 0.932
jnj
Java no jive (jnj) encodes the Smc6 subunit of the SMC5/6 protein complex. It is involved genotoxic stress and response to caffeine.
   
 
 0.914
Det
GEO07887p1; Deterin (Det) encodes a component of the chromosomal passenger complex involved in regulation of apoptosis and cytokinesis.
   
  
 0.899
mars
Mars (mars) encodes a microtubule-associated protein that shuttles between the mitotic spindle and the nucleus. It is required for mitotic spindle attachment to the centrosome; Belongs to the SAPAP family.
   
  
 0.898
smt3
Small ubiquitin-related modifier; Smt3 (smt3) encodes the only Drosophila SUMO family protein. It is required for embryonic patterning and mitosis. It may also have roles in wing patterning, Dpp signaling, and Ras/MAPK signaling. It localizes to the nucleus during interphase and to the kinetochores and midbodies during mitosis; Belongs to the ubiquitin family. SUMO subfamily.
