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

CCDC121Coiled-coil domain containing 121. (440 aa)    
Predicted Functional Partners:
TBC1D17
TBC1 domain family member 17; Probable GTPase-activating protein for Rab8; its transient association with Rab8 is mediated by OPTN. Inhibits Rab8-mediated endocytic trafficking, such as of transferrin receptor (TfR) and reduces Rab8 recruitnment to tubules emanating from the endocytic recycling compartment (ERC). Involved in regulation of autophagy. Mediates inhibition of autophagy caused by the OPTN variant GLC1E LYS- 50; the function requires its catalytic activity, however, the involved Rab is not known.
    
   0.817
C2orf16
Uncharacterized protein C2orf16; Chromosome 2 open reading frame 16.
   
  
 0.772
ZNF512
Zinc finger protein 512; May be involved in transcriptional regulation.
      
 0.729
KRTCAP3
Keratinocyte associated protein 3.
      
 0.654
TBC1D15
TBC1 domain family member 15; Acts as a GTPase activating protein for RAB7A. Does not act on RAB4, RAB5 or RAB6 (By similarity).
   
   0.618
NRBP1
Nuclear receptor-binding protein; May play a role in subcellular trafficking between the endoplasmic reticulum and Golgi apparatus through interactions with the Rho-type GTPases. Binding to the NS3 protein of dengue virus type 2 appears to subvert this activity into the alteration of the intracellular membrane structure associated with flaviviral replication; Belongs to the protein kinase superfamily. Ser/Thr protein kinase family.
      
 0.617
GPN1
GPN-loop GTPase 1; Small GTPase required for proper nuclear import of RNA polymerase II (RNAPII). May act at an RNAP assembly step prior to nuclear import. Forms an interface between the RNA polymerase II enzyme and chaperone/scaffolding proteins, suggesting that it is required to connect RNA polymerase II to regulators of protein complex formation. May be involved in nuclear localization of XPA.
      
 0.582
FNDC4
Fibronectin type III domain-containing protein 4; Acts as an anti-inflammatory factor in the intestine and colon. Binds to and acts on macrophages to downregulate pro- inflammatory gene expression. Affects key macrophage functions, including phagocytosis, by downregulating many key pathways for macrophage activation, partly via by STAT3 activation and signaling. May be required to dampen the immunological response in colitis.
      
 0.541
SLC4A1AP
Kanadaptin; Solute carrier family 4 member 1 adaptor protein.
   
  
 0.515
IFT172
Intraflagellar transport protein 172 homolog; Required for the maintenance and formation of cilia. Plays an indirect role in hedgehog (Hh) signaling, cilia being required for all activity of the hedgehog pathway (By similarity); Belongs to the IFT172 family.
