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

alphaKap4Importin subunit alpha; Nuclear import signal receptor activity; nuclear localization sequence binding. It is involved in the biological process described with: proteasome assembly; NLS-bearing protein import into nucleus; Belongs to the importin alpha family. (442 aa)    
Predicted Functional Partners:
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 [...]

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.

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 [...]

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).
   
 
 0.905
emb
Exportin-1; Receptor for the leucine-rich nuclear export signal (NES). Binds cooperatively to the NES on its target protein and to the small GTPase Ran in its active GTP-bound form. Involved in the export of dl, RpS2 and the pre-40S ribosome from the nucleus to the cytoplasm. Plays an important role in nuclear pore assembly by mediating nucleoporin condensation and biogenesis of annulate lamellae. Required for the function or maintenance of certain tissues such as brain and gut.

msk
D-Importin 7/RanBP7; Moleskin (msk) encodes an importin that contributes to protein import into the nucleus. It is involved in eye development, muscle attachment and wing cell fate specification.
   
 
 0.903
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.
   
 
 0.902
RanGAP
Ran GTPase-activating protein; GTPase activator for the nuclear Ras-related regulatory protein Ran, converting it to the putatively inactive GDP-bound state (By similarity). Trans-acting factor necessary for meiotic distortion. Distortion is only seen in individuals that carry the RanGAP tandem duplication and express a RanGAP truncated protein. Binding of truncated RanGAP product to the Responder(RSP) locus initiates events that lead to sperm dysfunction. During oogenesis, plays a role in the biogenesis of annulate lamellae containing nuclear pore complex components. Belongs to the RN [...]

Cbp80
Nuclear cap-binding protein subunit 1; Component of the cap-binding complex (CBC), which binds cotranscriptionally 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, Cbp80 does not bind directly capped RNAs [...]

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 [...]
