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

nosProtein nanos; Maternal RNA-binding protein that is required for germ cells proliferation and self-renewal. Acts by forming a complex with pum and brat that regulates translation and mRNA stability. The complex binds to the Nanos Response Element (NRE), a 16 bp sequence in the hb mRNA 3'-UTR and prevents its translation. Controls posterior development. Rescuing factor for the abdominal defect of posterior group mutants. The other posterior group genes are not required for nanos function but rather play a role in localization or distribution of nanos protein. (401 aa)    
Predicted Functional Partners:
pum
Maternal protein pumilio; Sequence-specific RNA-binding protein that acts as a post- transcriptional repressor by binding the 3'-UTR of mRNA targets. Binds to an RNA consensus sequence, the Pumilio Response Element (PRE), 5'- UGUANAUA-3', that is related to the Nanos Response Element (NRE). Mediates post-transcriptional repression of transcripts via different mechanisms: acts via direct recruitment of deadenylase complexes leading to translational inhibition and mRNA degradation (By similarity). Also mediates deadenylation-independent repression by promoting accessibility of miRNAs. Me [...]

Not1
Not1, isoform H; Not1 (Not1) encodes a poly(A)-specific ribonuclease involved in translation inhibition and ovarian follicle cell development.

osk
Maternal effect protein oskar; Organizes the germ plasm and directs localization of the posterior determinant nanos. Oskar protein is required to keep nos RNA and staufen protein at the posterior pole.

Sxl
Protein sex-lethal; Sex determination switch protein which controls sexual development by sex-specific splicing. Regulates dosage compensation in females by suppressing hyperactivation of X-linked genes. Expression of the embryo-specific isoform is under the control of primary sex- determining signal, which depends on the ratio of X chromosomes relative to autosomes (X:A ratio). Expression occurs in 2X:2A cells, but not in X:2A cells. The X:A ratio seems to be signaled by the relative concentration of the X-linked transcription factors SIS-A and SIS-B. As a result, the embryo-specific [...]

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 [...]

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.
   
 
 0.848
stau
Maternal effect protein staufen; RNA-binding protein which forms ribonucleoprotein complexes (RNPs) that play critical roles in the localization, translational repression and turnover of RNAs during embryogenesis, neurotransmission and neurogenesis. In the oocyte, essential for the localization of both the osk/oskar mRNA to the posterior pole and bcd/bicoid RNA to the anterior pole, and is therefore required for the correct anterior- posterior patterning of the developing embryo. Association with osk or bcd at their respective poles, appears to promote the formation and stabilization o [...]

aub
Protein aubergine; Acts via the piwi-interacting RNA (piRNA) metabolic process, which mediates the repression of transposable elements during meiosis by forming complexes composed of piRNAs and Piwi proteins and governs the methylation and subsequent repression of transposons. Directly binds piRNAs, a class of 24 to 30 nucleotide RNAs that are generated by a Dicer-independent mechanism and are primarily derived from transposons and other repeated sequence elements. In ovary, associates predominantly with antisense piRNAs that contain uridine at their 5' end. In testis, associates with [...]

smg
Smaug (smg) encodes the founding member of the SMAUG family of sequence-specific RNA-binding proteins. During the maternal-to-zygotic transition in early embryos, the smg product inhibits the translation and induces the degradation of hundreds of maternal mRNAs by recruitment of the CCR4-NOT deadenylase complex, thereby controlling embryonic patterning, activation of zygotic transcription, and early embryonic cell cycles.

hb
Protein hunchback; Gap class segmentation protein that controls development of head structures; Belongs to the hunchback C2H2-type zinc-finger protein family.
