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

Score
MSL5Branchpoint-bridging protein; Component of commitment complex; which defines first step in splicing pathway; essential protein that interacts with Mud2p and Prp40p, forming a bridge between the intron ends; also involved in nuclear retention of pre-mRNA; relocalizes to the cytosol in response to hypoxia. (476 aa)    
Predicted Functional Partners:
PRP5
Pre-mRNA-processing ATP-dependent RNA helicase PRP5; RNA helicase in the DEAD-box family; necessary for prespliceosome formation, bridges U1 and U2 snRNPs and enables stable U2 snRNP association with intron RNA; Belongs to the DEAD box helicase family. DDX46/PRP5 subfamily.
   
 
 0.999
SNU56
56 kDa U1 small nuclear ribonucleoprotein component; Component of U1 snRNP required for mRNA splicing via spliceosome; yeast specific, no metazoan counterpart; interacts with mRNA in commitment complex.
    
 0.999
NAM8
RNA binding protein, component of the U1 snRNP protein; mutants are defective in meiotic recombination and in formation of viable spores, involved in the formation of DSBs through meiosis-specific splicing of REC107 pre-mRNA; Nam8p regulon embraces the meiotic pre-mRNAs of REC107, HFM1, AMA1 SPO22 and PCH2; the putative RNA binding domains RRM2 and RRM3 are required for Nam8p meiotic function.
   
 0.999
PRP40
Pre-mRNA-processing protein PRP40; U1 snRNP protein involved in splicing; interacts with the branchpoint-binding protein during the formation of the second commitment complex.
    
 
 0.999
MUD2
Splicing factor MUD2; Protein involved in early pre-mRNA splicing; component of the pre-mRNA-U1 snRNP complex, the commitment complex; interacts with Msl5p/BBP splicing factor and Sub2p; similar to metazoan splicing factor U2AF65.
   
 0.999
PRP11
Pre-mRNA-splicing factor PRP11; Subunit of the SF3a splicing factor complex; required for spliceosome assembly.
   
 
 0.998
PRP21
Pre-mRNA-splicing factor PRP21; Subunit of the SF3a splicing factor complex; required for spliceosome assembly.
   
 
 0.998
PRP9
Pre-mRNA-splicing factor PRP9; Subunit of the SF3a splicing factor complex; required for spliceosome assembly; acts after the formation of the U1 snRNP-pre-mRNA complex; Belongs to the SF3A3 family.
   
 
 0.997
YHC1
U1 small nuclear ribonucleoprotein C; Component of the U1 snRNP complex required for pre-mRNA splicing; putative ortholog of human U1C protein, which is involved in formation of a complex between U1 snRNP and the pre-mRNA 5' splice site; Belongs to the U1 small nuclear ribonucleoprotein C family.
   
 0.994
CBC2
Nuclear cap-binding protein subunit 2; Small subunit of the heterodimeric cap binding complex with Sto1p; interacts with Npl3p, possibly to package mRNA for export from the nucleus; may have a role in telomere maintenance; contains an RNA-binding motif; Belongs to the RRM NCBP2 family.
