STRINGSTRING
URN1 protein (Saccharomyces cerevisiae) - STRING interaction network
"URN1" - Protein of unknown function containing WW and FF domains in Saccharomyces cerevisiae
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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

URN1Protein of unknown function containing WW and FF domains; overexpression causes accumulation of cells in G1 phase; Component of the spliceosome involved in mRNA processing (465 aa)    
Predicted Functional Partners:
CEF1
Essential splicing factor; associated with Prp19p and the spliceosome, contains an N-terminal c-Myb DNA binding motif necessary for cell viability but not for Prp19p association, evolutionarily conserved and homologous to S. pombe Cdc5p; Involved in pre-mRNA splicing and cell cycle control. Required for the binding of the NTC complex (or PRP19-associated complex) components to the spliceosome to mediate conformational rearrangement or to stabilize the structure of the spliceosome after U4 snRNA dissociation, which leads to spliceosome maturation. Its absence leads to an arrest of the c [...] (590 aa)

SNU66
Component of the U4/U6.U5 snRNP complex involved in pre-mRNA splicing via spliceosome; also required for pre-5S rRNA processing and may act in concert with Rnh70p; has homology to human SART-1; Component of the U4/U6.U5 tri-snRNP particle, one of the building blocks of the spliceosome. Required for pre-mRNA splicing (587 aa)
     
      0.914
SAC3
mRNA export factor; required for biogenesis of the small ribosomal subunit; component of TREX-2 complex (Sac3p-Thp1p-Sus1p-Cdc31p) involved in transcription elongation and mRNA export from the nucleus; involved in post-transcriptional tethering of active genes to the nuclear periphery and to non-nascent mRNP; similar to the human germinal center-associated nuclear protein (GANP); Component of the SAC3-THP1 complex, which functions in transcription-coupled mRNA export from the nucleus to the cytoplasm. SAC3-THP1 functions in docking export-competent ribonucleoprotein particles (mRNPs) t [...] (1301 aa)
     
      0.878
HUB1
Ubiquitin-like protein modifier; promotes alternative splicing of SRC1 pre-mRNA; binds non-covalently to the HIND domain of Snu66, may function in modification of Sph1p and Hbt1p, functionally complemented by the human or S. pombe ortholog; mechanis /.../ub1p adduct formation not yet clear; Forms conjugate with SPH1 and HBT1. Involved in morphogenesis (73 aa)
     
      0.869
PRP22
DEAH-box RNA-dependent ATPase/ATP-dependent RNA helicase, associates with lariat intermediates before the second catalytic step of splicing; mediates ATP-dependent mRNA release from the spliceosome and unwinds RNA duplexes; Acts late in the splicing of pre-mRNA. Mediates the release of the spliced mRNA from spliceosomes (1145 aa)
     
 
  0.866
SNU71
Component of U1 snRNP required for mRNA splicing via spliceosome; yeast specific, no metazoan counterpart; Component of the U1 snRNP particle, which recognizes and binds the 5’-splice site of pre-mRNA. Together with other non- snRNP factors, U1 snRNP forms the spliceosomal commitment complex, that targets pre-mRNA to the splicing pathway (620 aa)
     
 
  0.865
SNP1
Component of U1 snRNP required for mRNA splicing via spliceosome; substrate of the arginine methyltransferase Hmt1p; may interact with poly(A) polymerase to regulate polyadenylation; homolog of human U1 70K protein; Involved in nuclear mRNA splicing (300 aa)
     
 
  0.842
REB1
RNA polymerase I enhancer binding protein; DNA binding protein which binds to genes transcribed by both RNA polymerase I and RNA polymerase II; required for termination of RNA polymerase I transcription; DNA-binding protein that recognizes sites within both the enhancer and the promoter of rRNA transcription, as well as upstream of many genes transcribed by RNA polymerase II. It is essential for cell growth. May stimulate or inhibit transcription. Specifically recognizes the sequence 5’-CCGGGTA-3’ or 5’-CGGGTRR- 3’ (where R is any purine). A member of the general regulatory factors (GR [...] (810 aa)

PML1
Subunit of the RES complex, which is required for nuclear retention of unspliced pre-mRNAs; acts in the same pathway as Pml39p and Mlp1p; Required for efficient splicing and pre-mRNA nuclear retention (204 aa)
     
      0.778
NSI1
Protein of unknown function that may interact with ribosomes, based on co-purification experiments; Myb-like DNA-binding protein that may bind to the Ter region of rDNA; interacts physically with Fob1p; DNA-binding protein that recognizes sequence-specific replication termini (Ter sites) within rDNA (PubMed-14576157). Binds to rDNA terminator elements and mediates efficient RNA polymerase I transcription termination (PubMed-22805593). Required for rDNA silencing at the non-transcribed spacer 1 (NTS1). Promotes the association of SIR2 with NTS1 and contributes to maintenance of rDNA sta [...] (570 aa)
