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

SmnSurvival 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 [...] (226 aa)    
Predicted Functional Partners:
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.

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.

SmD1
Small ribonucleoprotein particle protein SmD1 (SmD1) encodes an RNA binding protein that forms a heterodimeric sub-complex with the product of SmD2. They function as part of the heteroheptameric ring complex Sm core, which is involved in the formation of spliceosomal small nuclear RNPs (U1, U2, U4 and U5), which together catalyze pre-mRNA splicing.

SmD2
Small ribonucleoprotein particle protein SmD2 (SmD2) encodes an RNA binding protein that forms a heterodimeric sub-complex with the product of SmD1. They function as part of the heteroheptameric ring complex Sm core, which is involved in the formation of spliceosomal small nuclear RNPs (U1, U2, U4 and U5), which together catalyze pre-mRNA splicing.

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.

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.

icln
Methylosome subunit pICln; Chaperone that regulates the assembly of spliceosomal U1, U2, U4 and U5 small nuclear ribonucleoproteins (snRNPs), the building blocks of the spliceosome. Thereby, plays an important role in the splicing of cellular pre-mRNAs. Most spliceosomal snRNPs contain a common set of Sm proteins SNRPB, SNRPD1, SNRPD2, SNRPD3, SNRPE, SNRPF and SNRPG that assemble in a heptameric protein ring on the Sm site of the small nuclear RNA to form the core snRNP. In the cytosol, the Sm proteins SNRPD1, SNRPD2, SNRPE, SNRPF and SNRPG are trapped in an inactive 6S pICln-Sm comple [...]

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.

SNRPG
Probable small nuclear ribonucleoprotein G; Plays role in pre-mRNA splicing as core component of the SMN- Sm complex that mediates spliceosomal snRNP assembly. Plays role in pre-mRNA splicing as component of the spliceosomal U1, U2, U4 and U5 small nuclear ribonucleoproteins (snRNPs), the building blocks of the spliceosome. Component of both the pre-catalytic spliceosome B complex and activated spliceosome C complexes. Is also a component of the minor U12 spliceosome (By similarity).
