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

sgo-1Shugoshin; Component of cell cycle checkpoints, which ensures chromosome segregation during meiosis and mitosis. During meiotic prophase, it is involved in the regulation of the synapsis checkpoint, which monitors whether homologous chromosomes have synapsed, and the DNA damage response. Plays a central role in chromosome cohesion during cell division by preventing premature dissociation of cohesin complex after prophase, when most of cohesin complex dissociates from chromosomes arms (By similarity). Belongs to the shugoshin family. (309 aa)    
Predicted Functional Partners:
bub-1
Mitotic checkpoint serine/threonine-protein kinase bub-1; Serine/threonine-protein kinase essential for spindle- assembly checkpoint signaling. Plays a key role in the recruitment of the checkpoint proteins bub-3, mdf-1 and mdf-2 to unattached kinetochores. mdf-1 recruitment is independent of bub-1 kinase activity. Has a role in the correct kinetochore localization of the spindly-like protein spdl-1. In addition, during meiotic anaphase I, controls the recruitment of hcp- 1/2 and klp-19 to the ring-shaped domain formed between chromosomes. Involved in chromosome alignment, chromosome h [...]

lab-1
Long arms of the bivalent protein 1; Involved in sister chromatid cohesion during mitosis and meiosis. In association with the gsp-2 phosphatase, it both restricts the localization and antagonizes the function of the air-2 kinase during meiosis I and mitosis to promote chromatid cohesion and spindle attachment. This in turn, drives germ cell immortality. Furthermore, may play a role in ensuring the timely assembly of the synaptonemal complex during prophase I of meiosis.
   
  
 0.873
air-2
Aurora/IPL1-related protein kinase 2; Serine/threonine-protein kinase component of the chromosomal passenger complex (CPC), a complex that acts as a key regulator of chromosome segregation and cytokinesis. The CPC complex has essential functions at the centromere in ensuring correct chromosome alignment and segregation. Required for histone H3 phosphorylation during segregation of homologous chromosomes in meiosis and mitosis. Required for histone H3 'Ser- 10' phosphorylation. Phosphorylates tlk-1 at 'Ser-634', which enhances its activity. Phosphorylates zen-4 at 'Ser- 680'. Required f [...]

sep-1
Separin homolog sep-1; Cysteine protease, which plays a central role in homologous chromosome separation during meiosis I and in sister chromatid separation during embryonic mitosis. Promotes chromosome/sister chromatid segregation by cleaving the scc-1 (mitosis) and rec-8 (meiosis) subunits of the cohesin complex at the onset of anaphase (Probable). May cleave histone H3-like protein cpar-1 during meiosis I metaphase- anaphase transition. Promotes cortical granule exocytosis after oocyte fertilization during the first meiotic anaphase. Essential for embryonic cytokinesis by regulating [...]

ZK430.5
Peptidase C50 domain-containing protein.
      
 0.815
gsp-2
Serine/threonine-protein phosphatase PP1-beta; Serine/threonine-protein phosphatase essential for chromosomal dynamics during meiosis and mitosis. During meiosis, promotes chromosomal cohesion and germline immortality via a small RNA- mediated genome silencing pathway. Antagonizes the function of air-2 kinase during meiosis I and mitosis to promote chromatid cohesion and spindle attachment. Dephosphorylates histone H3 at 'Ser-10' (Probable). Dephosphorylates histone H3 at 'Thr-3' (Probable). Also involved in the activation of chloride channel clh-3 during cell swelling and meiotic matu [...]

RING-type domain-containing protein.

coh-3
Rad21_Rec8 domain-containing protein.
   
  
 0.708
rec-8
Meiotic recombination protein rec-8; Plays a role in meiotic chromosome cohesion and segregation. Necessary for sister chromatid co- orientation and sister chromatid cohension until meiosis II. May also be required for repair of programmed meiotic double stranded breaks. During spermatogenesis, likely involved in spermatocyte centriole cohesion, thus preventing their separation during the second meiotic division. Belongs to the rad21 family. Highly divergent.
   
  
 0.695
smc-3
Structural maintenance of chromosomes protein 3; Involved in chromosome cohesion during cell cycle and in DNA repair. Involved in the repair of double strand breaks during mitosis and meiosis. Required for chromosome segregation during mitosis. Central component of cohesin complex. The cohesin complex is required for the cohesion of sister chromatids after DNA replication. The cohesin complex apparently forms a large proteinaceous ring within which sister chromatids can be trapped (By similarity). At anaphase, the complex is cleaved and dissociates from chromatin, allowing sister chrom [...]
