STRINGSTRING
REX4 protein (Saccharomyces cerevisiae) - STRING interaction network
"REX4" - Putative RNA exonuclease possibly involved in pre-rRNA processing and ribosome assembly 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

REX4Putative RNA exonuclease possibly involved in pre-rRNA processing and ribosome assembly; Exoribonuclease involved in ribosome biosynthesis. Involved in the processing of ITS1, the internal transcribed spacer localized between the 18S and 5.8S rRNAs (289 aa)    
Predicted Functional Partners:
SSF1
Constituent of 66S pre-ribosomal particles, required for ribosomal large subunit maturation; functionally redundant with Ssf2p; member of the Brix family; Required for biogenesis of the 60S ribosomal subunit (453 aa)
     
      0.988
POL30
Proliferating cell nuclear antigen (PCNA), functions as the sliding clamp for DNA polymerase delta; may function as a docking site for other proteins required for mitotic and meiotic chromosomal DNA replication and for DNA repair; This protein is an auxiliary protein of DNA polymerase delta and is involved in the control of eukaryotic DNA replication by increasing the polymerase’s processibility during elongation of the leading strand. Involved in DNA repair (258 aa)
     
  0.974
NOP4
Nucleolar protein, essential for processing and maturation of 27S pre-rRNA and large ribosomal subunit biogenesis; constituent of 66S pre-ribosomal particles; contains four RNA recognition motifs (RRMs); Required for 60S ribosomal subunit synthesis. Probably involved in the processing of 27S rRNA to produce mature 25S rRNA (685 aa)
     
 
  0.972
RNT1
RNAase III; involved in rDNA transcription and rRNA processing; also cleaves a stem-loop structure at the 3’ end of U2 snRNA to ensure formation of the correct U2 3’ end; involved in polyadenylation-independent transcription termination; DsRNA-specific nuclease that cleaves eukaryotic pre- ribosomal RNA at the U3 snoRNP-dependent A0 site in the 5’- external transcribed spacer (ETS) and in the 3’-ETS. In vitro, cleaves synthetic 5’-ETS RNA A0 site in the absence of snoRNA or other factors. Has an essential growth function in addition to pre-rRNA processing (471 aa)
     
   
  0.965
IMP4
Component of the SSU processome, which is required for pre-18S rRNA processing; interacts with Mpp10p; member of a superfamily of proteins that contain a sigma(70)-like motif and associate with RNAs; Required for the early cleavages at sites A0, A1 and A2 during 18S ribosomal pre-RNA processing (290 aa)
     
        0.962
BRX1
Nucleolar protein, constituent of 66S pre-ribosomal particles; depletion leads to defects in rRNA processing and a block in the assembly of large ribosomal subunits; possesses a sigma(70)-like RNA-binding motif; Required for biogenesis of the 60S ribosomal subunit (291 aa)
     
   
  0.959
TRM11
Catalytic subunit of an adoMet-dependent tRNA methyltransferase complex (Trm11p-Trm112p), required for the methylation of the guanosine nucleotide at position 10 (m2G10) in tRNAs; contains a THUMP domain and a methyltransferase domain; Catalytic subunit of an S-adenosyl-L-methionine- dependent tRNA methyltransferase complex that mediates the methylation of the guanosine nucleotide at position 10 (m2G10) in tRNAs (433 aa)
     
        0.954
RPF2
Essential protein involved in the processing of pre-rRNA and the assembly of the 60S ribosomal subunit; interacts with ribosomal protein L11; localizes predominantly to the nucleolus; constituent of 66S pre-ribosomal particles; Required for biogenesis of the 60S ribosomal subunit (344 aa)
     
      0.953
MAK16
Essential nuclear protein, constituent of 66S pre-ribosomal particles; required for maturation of 25S and 5.8S rRNAs; required for maintenance of M1 satellite double-stranded RNA of the L-A virus; Its role might be as part of the apparatus concerned with the nuclear events of the cell cycle (306 aa)
     
 
  0.950
RRS1
Essential protein that binds ribosomal protein L11; required for nuclear export of the 60S pre-ribosomal subunit during ribosome biogenesis; localizes to the nucleolus and in foci along nuclear periphery; cooperates with Ebp2p and Mps3p to mediate t /.../e clustering by binding Sir4p, but is not involved in telomere tethering; mouse homolog shows altered expression in Huntington’s disease model mice; Required for ribosome biogenesis (203 aa)
