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

cwoTranscription factor cwo; Plays a role in the regulation of circadian rhythms. Transcriptional repressor which inhibits Clock-mediated transcriptional activation by binding to E boxes in the promoters of Clock target genes and repressing their transcription. E box binding activity is time- dependent with higher binding activity seen in the early morning (zeitgeber time 2) than early evening (zeitgeber time 14) and is dependent on the presence of the circadian protein per. It is likely that per binds to Clock-cycle heterodimers, reducing their affinity for E box binding and allowing cwo [...] (698 aa)    
Predicted Functional Partners:
Clk
Circadian locomoter output cycles protein kaput; Circadian regulator that acts as a transcription factor and generates a rhythmic output with a period of about 24 hours. Oscillates in antiphase to the cycling observed for period (PER) and timeless (TIM). According to reaches peak abundance within several hours of the dark-light transition at ZT0 (zeitgeber 0), whereas describes bimodal oscillating expression with maximum at ZT5 and ZT23. Clock-cycle heterodimers activate cycling transcription of PER and TIM by binding to the E-box (5'-CACGTG-3') present in their promoters. Once induced [...]

cyc
Protein cycle; Putative transcription factor involved in the generation of biological rhythms. Activates cycling transcription of Period (PER) and Timeless (TIM) by binding to the E-box (5'-CACGTG-3') present in their promoters.
    
 0.961
Pdp1
PAR-domain protein 1 (Pdp1) encodes a member of the PAR domain bZip family of sequence-specific transcription factors. it regulates gene expression in muscles and in circadian clock neurons.
   
 
 0.927
vri
Vrille, isoform A; Vrille (vri) encodes a bZIP transcription factor acting as an enhancer of dpp phenotypes both in embryo and in wing. It is involved in hair and cell growth and in tracheal development. Vri is a clock-controlled gene acting as a repressor of the products of Clk and cry.

or
Adaptor protein complex AP-3 small chain sigma3; Orange (or) encodes an AP-3 adaptor complex component involved in ommochrome biosynthesis.
      
 0.912
per
Period circadian protein; Essential for biological clock functions. Determines the period length of circadian and ultradian rhythms; an increase in PER dosage leads to shortened circadian rhythms and a decrease leads to lengthened circadian rhythms. Essential for the circadian rhythmicity of locomotor activity, eclosion behavior, and for the rhythmic component of the male courtship song that originates in the thoracic nervous system. The biological cycle depends on the rhythmic formation and nuclear localization of the TIM-PER complex. Light induces the degradation of TIM, which promot [...]

tim
Protein timeless; Required for the production of circadian rhythms. The biological cycle depends on the rhythmic formation and nuclear localization of the TIM-PER complex. Light induces the degradation of TIM, which promotes elimination of PER. Nuclear activity of the heterodimer coordinatively regulates PER and TIM transcription through a negative feedback loop. Behaves as a negative element in circadian transcriptional loop. Does not appear to bind DNA, suggesting indirect transcriptional inhibition. Belongs to the timeless family.
      
 0.718
cry
Cryptochrome-1; Blue light-dependent regulator that is the input of the circadian feedback loop. Has no photolyase activity for cyclobutane pyrimidine dimers or 6-4 photoproducts. Regulation of expression by light suggests a role in photoreception for locomotor activity rhythms. Functions, together with per, as a transcriptional repressor required for the oscillation of peripheral circadian clocks and for the correct specification of clock cells. Genes directly activated by the transcription factors Clock (Clk) and cycle (cyc) are repressed by cry. Necessary for light-dependent magneto [...]
    
 
 0.711
sgg
Protein kinase shaggy; Required for several developmental events such as syncytial blastoderm formation and embryonic segmentation. Is involved in transcriptional regulation. Required for arm phosphorylation. Wg signaling operates by inactivating the sgg repression of en autoactivation. Negatively controls the neuromuscular junction (NMJ) growth in presynaptic motoneurons. Plays a role in the regulation of microtubule dynamics and actin cytoskeleton during embryogenesis. Required for phosphorylation of sra in activated eggs. Essential for completion of meiosis, possibly by triggering c [...]

phr6-4
(6-4)-photolyase, isoform A; (6-4)-photolyase (phr6-4) encodes an enzyme that repairs DNA damage induced by ultraviolet light. It uses blue light and cofactor FADH to reverse the pyrimidine(6-4)pyrimidone photoproduct.
