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

RanGAPRan 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 [...] (596 aa)    
Predicted Functional Partners:
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 [...]

lwr
Lesswright (lwr) encodes Ubc9, a SUMO conjugating enzyme that accepts SUMO from the SUMO activating enzyme and hands it off to the SUMO conjugation target. It has documented biological functions in innate immunity, meiosis, and anterior patterning of the embryo.
   
 0.999
Ran
GTP-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 [...]

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.

smt3
Small ubiquitin-related modifier; Smt3 (smt3) encodes the only Drosophila SUMO family protein. It is required for embryonic patterning and mitosis. It may also have roles in wing patterning, Dpp signaling, and Ras/MAPK signaling. It localizes to the nucleus during interphase and to the kinetochores and midbodies during mitosis; Belongs to the ubiquitin family. SUMO subfamily.

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.
   
 
 0.979
Ran-like
GTP-binding nuclear protein Ran-like; GTP-binding protein involved in nucleocytoplasmic transport. Required for the import of protein into the nucleus and also for RNA export.
   
 
 0.947
GCC185
GRIP and coiled-coil domain containing 185 kDa; Identical protein binding; ADP-ribosylation factor binding; Rab GTPase binding.
   
 
 0.929
Nup107
Nuclear pore complex protein Nup107; Plays a role in nuclear pore complex (NPC) assembly and maintenance. Required for nuclear import of Mad. Plays a role in double strand break repair by relocalizing the heterochromatic double strain breaks (DSBs) to the nuclear periphery as part of the homologous recombination (HR) repair process. Regulates cytokinesis during spermatocyte meiosis by maintaining type-B lamin Lam localization to the spindle envelope. Regulates female gonad development and oogenesis. Belongs to the nucleoporin Nup84/Nup107 family.

Ntf-2
Nuclear transport factor-2 (Ntf-2) is an essential gene regulating nuclear import. It encodes a protein that binds to the nuclear pore protein encoded by DCTN4-p62 and to the product of Ran and regulates the nuclear import of nuclear localization signal containing proteins.
