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

PQBP1Polyglutamine-binding protein 1; Intrinsically disordered protein that acts as a scaffold, and which is involved in different processes, such as pre-mRNA splicing, transcription regulation, innate immunity and neuron development. Interacts with splicing-related factors via the intrinsically disordered region and regulates alternative splicing of target pre-mRNA species. May suppress the ability of POU3F2 to transactivate the DRD1 gene in a POU3F2 dependent manner. Can activate transcription directly or via association with the transcription machinery. May be involved in ATXN1 mutant-in [...] (265 aa)    
Predicted Functional Partners:
WBP11
WW domain-binding protein 11; Activates pre-mRNA splicing. May inhibit PP1 phosphatase activity.
   
 0.994
TXNL4A
Thioredoxin-like protein 4A; Plays role in pre-mRNA splicing as component of the U5 snRNP and U4/U6-U5 tri-snRNP complexes that are involved in spliceosome assembly, and as component of the precatalytic spliceosome (spliceosome B complex); Belongs to the DIM1 family.
   
 0.994
ATXN1
Ataxin-1; Chromatin-binding factor that repress Notch signaling in the absence of Notch intracellular domain by acting as a CBF1 corepressor. Binds to the HEY promoter and might assist, along with NCOR2, RBPJ- mediated repression. Binds RNA in vitro. May be involved in RNA metabolism. In concert with CIC and ATXN1L, involved in brain development (By similarity).
    
 
 0.946
WBP4
WW domain-binding protein 4; Involved in pre-mRNA splicing as a component of the spliceosome. May play a role in cross-intron bridging of U1 and U2 snRNPs in the mammalian A complex.
   
 
 0.913
UBL5
Ubiquitin-like protein 5; Ubiquitin like 5.
   
 0.890
ZMAT2
Zinc finger matrin-type protein 2; Involved in pre-mRNA splicing as a component of the spliceosome.
   
 
 0.882
MFAP1
Microfibrillar-associated protein 1; Involved in pre-mRNA splicing as a component of the spliceosome; Belongs to the MFAP1 family.
   
 
 0.873
SMU1
WD40 repeat-containing protein SMU1, N-terminally processed; Involved in pre-mRNA splicing as a component of the spliceosome. Regulates alternative splicing of the HSPG2 pre-mRNA (By similarity). Required for normal accumulation of IK. Required for normal mitotic spindle assembly and normal progress through mitosis (By similarity). Belongs to the WD repeat SMU1 family.
   
 
 0.871
PRPF38A
Pre-mRNA-splicing factor 38A; Involved in pre-mRNA splicing as a component of the spliceosome.
   
 
 0.868
FTSJ1
Putative tRNA (cytidine(32)/guanosine(34)-2'-O)-methyltransferase; Methylates the 2'-O-ribose of nucleotides at positions 32 and 34 of the tRNA anticodon loop of substrate tRNAs; Belongs to the class I-like SAM-binding methyltransferase superfamily. RNA methyltransferase RlmE family. TRM7 subfamily.
