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

SnupSnurportin-1; Snurportin (Snup) encodes a transport adaptor protein that functions together with the product of msk to carry out nuclear import of small nuclear RNPs. It binds specifically to the 2,2,7-trimethylguanosine cap structure that is present on mature snRNAs. Snup is an essential gene, and the protein shuttles between the cytoplasm and the nucleus. (351 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.

CG42304
LD20870p; DNA binding; nucleosome binding.
 
 
 
 0.989
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.

Smn
Survival motor neuron protein; The SMN complex plays an essential role in spliceosomal snRNP assembly in the cytoplasm, is required for pre-mRNA splicing in the nucleus and acts as a chaperone that discriminates target and non- target RNAs of Sm proteins. Required for normal expression of spliceosomal snRNAs and for U12 intron splicing. Required in cholinergic neurons, but not in motor neurons, to ensure correct splicing and proper levels of stas mRNA and normal neurotransmitter release by motor neurons. However, Smn is required in motor neurons, but not in cholinergic neurons, for nor [...]

Lsm10
Lsm10 (Lsm10) encodes a core component of the U7 snRNP complex, which functions in 3' end processing of the non-polyadenylated, replication-dependent histone mRNAs. The product of Lsm10 is part of the heptameric Sm ring complex that binds directly to U7 snRNA. It replaces the protein encoded by SmD1 in the canonical heptameric Sm protein ring that binds spliceosomal snRNAs.

Gem3
Gemin3, isoform A; Gemin 3 (Gem3) encodes an RNA helicase and a member of the SMN-Gemins complex. It is a component of the cytoplasmic U snRNP body and nuclear gems. It is required in the motor system for viability, neuromuscular junction development and motor behaviour.
    
 0.941
Gem2
Protein Gemin2; The SMN complex plays an essential role in spliceosomal snRNP assembly in the cytoplasm, is required for pre-mRNA splicing in the nucleus and acts as a chaperone that discriminates target and non- target RNAs of Sm proteins.
     
 0.927
rig
Rigor mortis (rig) encodes a component of the cytoplasmic U snRNP body and a member of the SMN-Gemins complex. It is required in the motor system for viability and motor behaviour. It also works as a nuclear receptor interacting protein required for ecdysone signalling during larval development.
     
 0.924
Lsm11
FI05704p; Lsm11 (Lsm11) encodes one of the seven proteins that form a heptameric Sm ring in the U7 snRNP, which is a key factor involved in 3' end processing of histone pre-mRNAs. It interacts with the product of FLASH. The two interacting proteins form a biochemical platform that recruits a number of polyadenylation subunits to the U7 snRNP, including the products of Sym, Cpsf100, Cpsf73 and CstF64.

Nup214
Nuclear pore complex protein Nup214; Serves as a docking site in the receptor-mediated import of substrates across the nuclear pore complex including emb, RanGAP and phosphorylated Mad. Protects mbo/Nup88 from proteasomal degradation at the nuclear pore. Together with mbo/Nup88, sequesters emb in the cytoplasm and thereby attenuates nuclear export signal (NES)-mediated nuclear export. Together with mbo/Nup88, required for the nuclear import of the Rel family transcription factors dorsal (dl) and Dorsal-related immunity factor (Dif) and the activation of an immune response.
