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

PsiP-element somatic inhibitor (Psi) encodes a protein that has dual roles in RNA processing and transcriptional regulation. It is required for activating Myc transcription. (797 aa)    
Predicted Functional Partners:
14-3-3zeta
14-3-3 protein zeta; Required in Raf-dependent cell proliferation and photoreceptor differentiation during eye development. Acts upstream of Raf and downstream of Ras, and is essential for viability. Acts as a negative regulator of the slo calcium channel via its interaction with slo-binding protein slob. Inhibits yki activity by restricting its nuclear localization. Binds to and promotes the activity of phosphoinositide 3-kinase Pi3K68D which converts phosphatidylinositol to phosphatidylinositol-3-phosphate and promotes maturation of early endosomes.

hfp
Poly(U)-binding-splicing factor half pint; Splicing factor that regulates oogenesis and controls both mitosis and mRNA localization in the germline by regulating mRNA splicing of a subset of genes within the ovary. Probably acts by regulating the alternative splice site selection of the otu transcript. Also regulates the alternative splicing of eIF4E1 and grk, while it is not involved in the splicing of par-1, sqd and psq. Belongs to the RRM half pint family.

Akt1
RAC serine/threonine-protein kinase; Serine/threonine kinase involved in various developmental processes. During early embryogenesis, acts as a survival protein. During mid-embryogenesis, phosphorylates and activates trh, a transcription factor required for tracheal cell fate determination. Also regulates tracheal cell migration. Later in development, acts downstream of PI3K and Pk61C/PDK1 in the insulin receptor transduction pathway which regulates cell growth and organ size, by phosphorylating and antagonizing FOXO transcription factor. Controls follicle cell size during oogenesis. M [...]

how
Protein held out wings; Required for integrin-mediated cell-adhesion in wing blade. Vital role in steroid regulation of muscle development and to control heart rate. Required during embryogenesis, in late stages of somatic muscle development, for myotube migration and during metamorphosis for muscle reorganization.

snRNP-U1-70K
Small ribonucleoprotein particle U1 subunit 70K (snRNP-U1-70K) encodes a protein component of the U1 snRNP. The U1 snRNP combines with other snRNPs on the pre-mRNA to assemble a spliceosome.
   
 
 0.641
HnRNP-K
Heterogeneous nuclear ribonucleoprotein K (HnRNP-K) encodes a member of the hnRNP family of DNA/RNA binding proteins. It localizes, along with other hnRNPs, in nucleoplasmic omega speckles. It is involved in gene regulation, post-transcriptional RNA processing and RNA transport.
   
 
 0.612
glo
Glorund, isoform A; Glorund (glo) encodes a hnRNP F/H family RNA-binding protein that binds directly to nos mRNA and regulates its translation during late stages of oogenesis. The functions of the product of glo include nurse cell nuclear chromatin organization, axis patterning as well as being required for viability to adulthood.
   
 
 0.596
rump
Rumpelstiltskin, isoform A; Rumpelstiltskin (rump) encodes the Drosophila hnRNP M homolog. It binds to nos and osk mRNAs and plays a role in mRNA localization to the germ plasm by diffusion/entrapment during late stages of oogenesis. It also binds to exonic splicing enhancers on pre-mRNA targets, implicating it as a splicing factor.
   
 
 0.584
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 [...]

mub
Mushroom-body expressed, isoform K; Mushroom-body expressed (mub) encodes a protein involved in thermosensory behavior and regulation of alternative mRNA splicing.
