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:
some 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

WBP4WW domain-binding protein 4; Promotes pre-mRNA splicing. A spliceosome-associated protein; may play a role in cross-intron bridging of U1 and U2 snRNPs in the mammalian A complex (376 aa)    
Predicted Functional Partners:
SNRPB
Small nuclear ribonucleoprotein-associated proteins B and B; Core component of the 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. As part of the U7 snRNP it is involved in histone 3'-end processing

SNRPB2
U2 small nuclear ribonucleoprotein B'; Involved in pre-mRNA splicing. This protein is associated with snRNP U2. It binds stem loop IV of U2 snRNA only in presence of the U2A' protein; RNA binding motif containing
    
 0.997
PRPF31
U4/U6 small nuclear ribonucleoprotein Prp31; Involved in pre-mRNA splicing. Required for the assembly of the U4/U5/U6 tri-snRNP complex, one of the building blocks of the spliceosome; U4/U6 small nucleolar ribonucleoprotein
    
 0.996
SNRNP200
U5 small nuclear ribonucleoprotein 200 kDa helicase; RNA helicase that plays an essential role in pre-mRNA splicing as component of the U5 snRNP and U4/U6-U5 tri-snRNP complexes. Involved in spliceosome assembly, activation and disassembly. Mediates changes in the dynamic network of RNA-RNA interactions in the spliceosome. Catalyzes the ATP-dependent unwinding of U4/U6 RNA duplices, an essential step in the assembly of a catalytically active spliceosome

MFAP1
Microfibrillar-associated protein 1; May be required for pre-mRNA splicing; Spliceosomal B complex
   
 0.993
ZMAT2
U4/U6.U5 tri-snRNP component SNU23; Zinc finger matrin-type 2; Spliceosomal B complex
   
 0.993
SF3B4
Splicing factor 3B subunit 4; Involved in pre-mRNA splicing as a component of the splicing factor SF3B complex. SF3B complex is required for 'A' complex assembly formed by the stable binding of U2 snRNP to the branchpoint sequence (BPS) in pre-mRNA. Sequence independent binding of SF3A/SF3B complex upstream of the branch site is essential, it may anchor U2 snRNP to the pre-mRNA. May also be involved in the assembly of the 'E' complex. SF3B4 has been found in complex 'B' and 'C' as well. Belongs also to the minor U12-dependent spliceosome, which is involved in the splicing of rare class [...]
    
 0.992
SMU1
SMU1, DNA replication regulator and spliceosomal factor; WD40 repeat-containing protein SMU1; Auxiliary spliceosomal protein that regulates selection of alternative splice sites in a small set of target pre-mRNA species (Probable). Regulates alternative splicing of the HSPG2 pre-mRNA (By similarity). Required for normal mitotic spindle assembly and normal progress through mitosis. Required for normal accumulation of IK; Belongs to the WD repeat SMU1 family
   
 0.991
SF3A1
Splicing factor 3A subunit 1; Subunit of the splicing factor SF3A required for 'A' complex assembly formed by the stable binding of U2 snRNP to the branchpoint sequence (BPS) in pre-mRNA. Sequence independent binding of SF3A/SF3B complex upstream of the branch site is essential, it may anchor U2 snRNP to the pre-mRNA. May also be involved in the assembly of the 'E' complex; U2 small nucleolar ribonucleoprotein

PRPF38A
Pre-mRNA-splicing factor 38A; May be required for pre-mRNA splicing; Belongs to the PRP38 family
