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

PenImportin subunit alpha; Pendulin (Pen) encodes a member of the Importin-alpha protein family, an essential adaptor in the Ran-GTP nuclear transport cycle binding a cargo protein to the nuclear import receptor encoded by Fs(2)Ket. In addition to nuclear protein import, the product of Pen is involved in centrosome duplication, mitotic spindle dynamics, nuclear envelope assembly, ring canal formation in the female germline, geotaxic behaviour and perception of pain. (522 aa)    
Predicted Functional Partners:
Fs(2)Ket
Importin subunit beta; Required for nuclear protein import and mediates docking of import substrate to distinct nucleoporins. In Drosophila, may not function as a snRNP import receptor as it does not interact with components of the snRNP complex such as snRNP U1, U2, U4/U6 and Snup.

nbs
Nibrin; Nbs (nbs) encodes a component of the conserved MRN complex, which plays an important role in the repair of DNA double strand breaks. The product of nbs is required to prevent chromosome breakage, interacts with the telomere capping complex and prevents telomeric fusions.

Nup153
Nuclear pore complex protein Nup153; Component of the nuclear pore complex (NPC), a complex required for the trafficking across the nuclear envelope. Functions as a scaffolding element in the nuclear phase of the NPC. Essential for the nuclear import of nuclear localization signal (NLS)-containing proteins in a Importin alpha/Importin beta receptor-dependent manner. Required for nuclear import of Mad. Plays a role in chromosomal organization and gene expression regulation; stimulates transcription by promoting the formation of an open chromatin environment. Binds chromatin to nucleopor [...]

Nup50
Nuclear pore complex protein Nup50; Component of the nuclear pore complex that has a direct role in nuclear protein import (By similarity). Actively displaces NLSs from importin-alpha, and facilitates disassembly of the importin-alpha:beta- cargo complex and importin recycling (By similarity). Binds to transcriptionally active chromatin sites when located in the nucleoplasm and is involved in transcriptional activation.
   
 
 0.856
Cse1
Exportin-2; Export receptor for importin alpha. Mediates importin-alpha re-export from the nucleus to the cytoplasm after import substrates have been released into the nucleoplasm (By similarity).
   
 
 0.846
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.
   
    0.836
Nup358
E3 SUMO-protein ligase RanBP2; E3 SUMO-protein ligase (By similarity). Component of the nuclear pore complex (NPC), a complex required for trafficking across the nuclear envelope. Required for nuclear import of nuclear localization signal (NLS)-containing proteins in an importin alpha/importin beta-dependent manner, but also for the nuclear import of specific proteins such as phosphorylated Mad or the sesquiterpenoid juvenile hormone receptor Met as part of the juvenile hormone signal transduction pathway. Plays a role in nuclear mRNA export by recruiting the mRNA transport complex com [...]

Rcc1
Regulator of chromosome condensation 1 (Rcc1) encodes the guanine-nucleotide exchange factor for the product of Ran. It promotes the nucleo-cytoplasmic shuttling of specific proteins and regulates chromatin condensation. The roles of Rcc1 product include cell proliferation, cell survival, apoptosis, epigenetic regulation, and neuronal specification.

Cbp20
Nuclear cap-binding protein subunit 2; Component of the cap-binding complex (CBC), which binds co- transcriptionally to the 5' cap of pre-mRNAs and is involved in various processes such as pre-mRNA splicing and RNA-mediated gene silencing (RNAi). The CBC complex is involved in miRNA-mediated RNA interference via its interaction with Ars2 and is required for primary microRNAs (miRNAs) processing. Also involved in innate immunity via the short interfering RNAs (siRNAs) processing machinery by restricting the viral RNA production. In the CBC complex, Cbp20 recognizes and binds capped RNAs [...]

Als2
Alsin homolog; Has guanine nucleotide exchange factor (GEF) activity towards Rab5. Promotes the exchange of GDP to GTP, converting inactive GDP- bound Rab5 into its active GTP-bound form.
