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

RanGTP-binding nuclear protein Ran; GTPase involved in nucleocytoplasmic transport, participating both to the import and the export from the nucleus of proteins and RNAs. Switches between a cytoplasmic GDP- and a nuclear GTP-bound state by nucleotide exchange and GTP hydrolysis. Nuclear import receptors such as importin beta bind their substrates only in the absence of GTP- bound RAN and release them upon direct interaction with GTP-bound RAN, while export receptors behave in the opposite way. Thereby, RAN controls cargo loading and release by transport receptors in the proper compartment [...] (216 aa)    
Predicted Functional Partners:
Ranbp21
Ranbp21, isoform A; RNA binding; nuclear export signal receptor activity; Ran GTPase binding. It is involved in the biological process described with: regulation of protein export from nucleus; RNA export from nucleus.

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.
   
 0.995
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 [...]

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 [...]
   
 0.988
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.
   
 0.980
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.

eEF1alpha1
Elongation factor 1-alpha 1; This protein promotes the GTP-dependent binding of aminoacyl- tRNA to the A-site of ribosomes during protein biosynthesis; Belongs to the TRAFAC class translation factor GTPase superfamily. Classic translation factor GTPase family. EF-Tu/EF-1A subfamily.
   
 
 0.959
eEF1alpha2
Elongation factor 1-alpha 2; This protein promotes the GTP-dependent binding of aminoacyl- tRNA to the A-site of ribosomes during protein biosynthesis; Belongs to the TRAFAC class translation factor GTPase superfamily. Classic translation factor GTPase family. EF-Tu/EF-1A subfamily.

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 [...]

eEF5
Eukaryotic translation initiation factor 5A; mRNA-binding protein involved in translation elongation. Has an important function at the level of mRNA turnover, probably acting downstream of decapping. Involved in actin dynamics and cell cycle progression, mRNA decay and probably in a pathway involved in stress response and maintenance of cell wall integrity. Functions as a regulator of apoptosis; Belongs to the eIF-5A family.
