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

SmESmall ribonucleoprotein particle protein SmE (SmE) encodes an RNA binding protein that functions as part of a heteroheptameric ring structure called the Sm core. This complex binds to spliceosomal small nuclear RNAs (e.g. U1, U2, U4 and U5) and helps to carry out pre-mRNA splicing. It also forms a heterotrimeric sub-complex with the products of SmF and SNRPG. (94 aa)    
Predicted Functional Partners:
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).

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.

SmD3
Small ribonucleoprotein particle protein SmD3 (SmD3) encodes an RNA binding protein that forms a heterodimeric sub-complex with the product of SmB. 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. The product of SmD3 also has a function in germline specification, as it is required for localization of the product of osk to the posterior pole of the oocyte.

SmF
Small ribonucleoprotein particle protein SmF (SmF) encodes an RNA binding protein that functions as part of a heteroheptameric ring structure called the Sm core. This complex binds to spliceosomal small nuclear RNAs (e.g. U1, U2, U4 and U5) and helps to carry out pre-mRNA splicing. It also forms a heterotrimeric sub-complex with the products of SmE and SNRPG.

SmB
Small ribonucleoprotein particle protein SmB (SmB) encodes an RNA binding protein that forms a heterodimeric sub-complex with the product of SmD3. 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; Belongs to the snRNP SmB/SmN family.

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.

snf
U1 small nuclear ribonucleoprotein A; Binds stem loop II of U1 snRNA. It is the first snRNP to interact with pre-mRNA. This interaction is required for the subsequent binding of U2 snRNP and the U4/U6/U5 tri-snRNP (By similarity). Plays a role in regulating sex-lethal splicing; Belongs to the RRM U1 A/B'' family.

Sf3b5
Splicing factor 3B subunit 5; Involved in pre-mRNA splicing as component of spliceosome. As part of the spliceosome complex, plays a role in the regulation of spermatogonial differentiation. When associated with the SAGA transcription regulatory histone acetylation (HAT) complex, might be involved in the transcriptional activation of a subset of SAGA-regulated genes ; Belongs to the SF3B5 family.
