STRINGSTRING
REB1 protein (Saccharomyces cerevisiae) - STRING interaction network
"REB1" - RNA polymerase I enhancer binding protein 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

REB1RNA 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)    
Predicted Functional Partners:
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)
     
 
  0.937
MSL5
Component of the commitment complex, which defines the first step in the 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; Required for pre-spliceosome formation, which is the first step of pre-mRNA splicing. 2 commitment complexes, CC1 and CC2, have been defined. CC1 is a basal complex dependent only on the 5’-splice site. CC2 is a complex of lower mobility and is dependent on a branchpoint as well as a 5’-splice site region. This protein is involved in CC2 formation where [...] (476 aa)

PRP3
Splicing factor, component of the U4/U6-U5 snRNP complex; Participates in pre-mRNA splicing. Part of the U4/U5/U6 tri-snRNP complex, one of the building blocks of the spliceosome (469 aa)
     
 
  0.917
PRP46
Member of the NineTeen Complex (NTC) that contains Prp19p and stabilizes U6 snRNA in catalytic forms of the spliceosome containing U2, U5, and U6 snRNAs; Involved in pre-mRNA splicing. May also be required for cell cycle progression at G2/M (By similarity) (451 aa)
     
 
  0.916
PRP19
Splicing factor associated with the spliceosome; contains a U-box, a motif found in a class of ubiquitin ligases, and a WD40 domain; Probable ubiquitin-protein ligase involved in pre-mRNA splicing. Acts as a central component of the NTC complex (or PRP19-associated complex) that associates to the spliceosome to mediate conformational rearrangement or to stabilize the structure of the spliceosome after U4 snRNA dissociation, which leads to spliceosome maturation. It is also probably involved in DNA repair (503 aa)
     
 
  0.896
PRP8
Component of the U4/U6-U5 snRNP complex, involved in the second catalytic step of splicing; mutations of human Prp8 cause retinitis pigmentosa; Functions as a scaffold that mediates the ordered assembly of spliceosomal proteins and snRNAs. Required for association of BRR2 with the spliceosomal U5 snRNP, and the subsequent assembly of the U4/U6-U5 tri-snRNP complex. Functions as scaffold that positions spliceosomal U2, U5 and U6 snRNAs at splice sites on pre-mRNA substrates, so that splicing can occur. Interacts with both the 5’ and the 3’ splice site, as well as the branch region. Has [...] (2413 aa)
     
 
  0.873
RFX1
Major transcriptional repressor of DNA-damage-regulated genes, recruits repressors Tup1p and Cyc8p to their promoters; involved in DNA damage and replication checkpoint pathway; similar to a family of mammalian DNA binding RFX1-4 proteins (811 aa)
     
 
  0.852
ABF1
DNA binding protein with possible chromatin-reorganizing activity involved in transcriptional activation, gene silencing, and DNA replication and repair; General regulatory factor (GRF) that contributes to transcriptional activation of a large number of genes, as well as to DNA replication, silencing and telomere structure. Involved in the transcription activation of a subset of ribosomal protein genes. Binds the ARS-elements found in many promoters. Binds to the sequence 5’-TCN(7)ACG-3’. Influences on genome-wide nucleosome occupancy and affects chromatin structure, and probably dynam [...] (731 aa)
     
   
  0.848
RSC1
Component of the RSC chromatin remodeling complex; required for expression of mid-late sporulation-specific genes; contains two essential bromodomains, a bromo-adjacent homology (BAH) domain, and an AT hook; Component of the chromatin structure remodeling complex (RSC), which is involved in transcription regulation and nucleosome positioning. RSC is responsible for the transfer of a histone octamer from a nucleosome core particle to naked DNA. The reaction requires ATP and involves an activated RSC-nucleosome intermediate. Remodeling reaction also involves DNA translocation, DNA twist [...] (928 aa)
     
  0.840
PRP11
Subunit of the SF3a splicing factor complex, required for spliceosome assembly; mRNA splicing factors, PRP9, PRP11, and PRP21, are necessary for addition of the U2 snRNP to the pre-mRNA in an early step of spliceosome assembly (266 aa)
