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

ypsYpsilon schachtel, isoform A; Nucleic acid binding; protein binding; mRNA binding. It is involved in the biological process described with: oogenesis; mRNA splicing, via spliceosome; regulation of gene expression. (352 aa)    
Predicted Functional Partners:
me31B
ATP-dependent RNA helicase me31b; ATP-dependent RNA helicase which is a core component of a variety of ribonucleoprotein complexes (RNPs) that play critical roles in translational repression and mRNA decapping during embryogenesis, oogenesis, neurogenesis and neurotransmission. Recruits core components and translational repressors to some RNP complexes, and mediates RNP aggregation into processing granules such as P-bodies. As part of a RNP complex containing tral, eIF4E1, cup, and pAbp, involved in RNP-mediated translational repression of maternal mRNAs during oogenesis and embryogene [...]

tral
Trailer hitch (tral) encodes a protein required for oocyte dorsoventral patterning via actin and microtubule cytoskeleton organization.
   
 0.978
eIF4E1
Eukaryotic translation initiation factor 4E1; Recognizes and binds the 7-methylguanosine-containing mRNA cap during an early step in the initiation of protein synthesis and facilitates ribosome binding by inducing the unwinding of the mRNAs secondary structures. In 0-1 hour embryos, forms a complex with me31B, cup, tral and pAbp which binds to various mRNAs including maternal mRNAs, and downregulates their expression during the maternal-to-zygotic transition. Belongs to the eukaryotic initiation factor 4E family.
   
 0.942
orb
Oo18 RNA-binding protein (orb) encodes a RNA-binding protein required for the formation of the egg chamber and establishment of polarity during oogenesis. It is involved in mRNA polyadenylation and the regulation of osk mRNA translation.
   
 0.925
cup
Protein cup; Adapter protein that plays a central role in localization of transcripts in the oocyte and in young embryos. Maintains RNA targets in a repressed state by promoting their deadenylation and protects deadenylated mRNAs from further degradation. Binds to and recruits eIF-4E to the 3'-UTR of some mRNA targets which prevents interaction between eIF4E1 and eIF4G. This may contribute to translational repression but does not appear to be necessary for it to occur. Can promote translational repression independently of deadenylation and eIF4E1 binding. Required for correct localizat [...]
   
 0.899
pAbp
Polyadenylate-binding protein; Binds the poly(A) tail of mRNA. Since it interacts with the cap-associating translation initiation factor eIF4G, it is likely that it functions by linking Atx2 to the cap-binding complex. Forms a complex with tyf and Atx2 which functions in adult circadian pacemaker neurons to sustain circadian rhythms likely by switching between activator and repressor modes of post-transcriptional regulation via interaction with Lsm12a or me31B, respectively. The activator complex (Atx2-tyf activator complex) activates the TYF-dependent translation of per to maintain 24 [...]
   
 
 0.853
Pur-alpha
Purine-rich binding protein-alpha (Pur-alpha) encodes a DNA- and RNA-binding protein involved in the regulation of transcription and cell-cycle. In the cytoplasm it is found in motile RNPs, indicating a role in RNA localization.
    
 0.852
exu
Maternal protein exuperantia; Ensures the proper localization of the mRNA of the bicoid gene to the anterior regions of the oocyte thus playing a fundamental role in the establishment of the polarity of the oocyte. May bind the bcd mRNA.
    
 
 0.844
Fmr1
Synaptic functional regulator FMR1; Polyribosome-associated RNA-binding protein that plays a role in neuronal development and synaptic plasticity through the regulation of protein synthesis of mRNAs. Plays a role as a negative translational regulator of specific mRNAs. Represses translation of the microtubule-associated protein futsch mRNA to regulate microtubule-dependent synaptic growth and function. May also be involved in microRNA (miRNA)-mediated translational suppression as part of the RNA-induced silencing complex (RISC). Required for stability of the central pair of microtubule [...]
    
 0.841
btz
Barentsz, isoform D; Barentsz (btz) encodes a component of the exon junction complex that is recruited to spliced mRNAs to mark where introns have been removed. It is required for the posterior localization of osk mRNA.
