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

Frq2Frequenin 2 (Frq2) encodes s protein that binds calcium and interacts with the guanyl exchange factor encoded by ric8a to regulate the number of synapses and the probability of neurotransmitter release per synapse. (187 aa)    
Predicted Functional Partners:
fwd
Four wheel drive (fwd) encodes a Golgi-localized lipid kinase that synthesizes phosphatidylinositol 4-phosphate from phosphatidylinositol. It is involved in spermatocyte cytokinesis and male fertility; Belongs to the PI3/PI4-kinase family.

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.
      
 0.790
ric8a
Synembryn; Guanine nucleotide exchange factor (GEF), which can activate some, but not all, G-alpha proteins independently of G-protein coupled receptors. Acts by exchanging bound GDP for free GTP. Plays a key role in asymmetric spindle positioning, a step for asymmetric cell division that generates cell diversity during development by activating G(i) alpha protein independently of G-protein coupled receptors. In addition to its GEF activity, it plays an essential role in cortical subcellular localization of heterotrimeric G proteins, suggesting it acts as a facilitator of G-alpha funct [...]

CASK
Peripheral plasma membrane protein CASK; CASK (CASK) encodes a member of the MAGUK family of scaffolding proteins. In epithelial tissues, the product of CASK functions as an adhesion molecule involved in cell proliferation, cytoskeletal remodeling and cell migration. In neurons, the product of CASK serves as a scaffold for a number of signaling and transmembrane molecules and is involved in synaptic development and plasticity.

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 [...]

csw
Tyrosine-protein phosphatase corkscrew; Required in all receptor tyrosine kinase signaling pathways. Functions downstream of the receptor tyrosine kinase torso, acting in concert with D-Raf via tailless. Also functions downstream of Egfr (epidermal growth factor receptor) and btl (fibroblast growth factor receptor). The SH2 domain suggests that csw effects its role by mediating heteromeric protein interactions. Maternally required for normal determination of cell fates at the termini of the embryo. Required for cell fate specification of the ventral ectoderm, in the developing embryoni [...]

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.

Crys
Crystallin, isoform A; Crystallin (Crys) encodes a chitin binding protein involved in the formation of the peritrophic matrix, a chitinous layer lining the midgut.
    
 
 0.605
Lrrk
Leucine-rich repeat kinase (Lrrk) encodes a large Ser/Thr kinase involved in mRNA translational control, cytoskeleton regulation, vesicle trafficking, autophagy, and immune response.
