STRINGSTRING
DBP1 protein (Saccharomyces cerevisiae) - STRING interaction network
"DBP1" - Putative ATP-dependent RNA helicase of the DEAD-box protein family 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

DBP1Putative ATP-dependent RNA helicase of the DEAD-box protein family; mutants show reduced stability of the 40S ribosomal subunit scanning through 5’ untranslated regions of mRNAs; ATP-binding RNA helicase involved in translation initiation. Remodels RNA in response to ADP and ATP concentrations by facilitating disruption, but also formation of RNA duplexes (By similarity). Redundant to DED1, may be required in conditions in which DED1 expression is decreased (617 aa)    
Predicted Functional Partners:
SNU114
GTPase component of U5 snRNP involved in mRNA splicing via spliceosome; binds directly to U5 snRNA; proposed to be involved in conformational changes of the spliceosome; similarity to ribosomal translocation factor EF-2; Component of the U5 snRNP complex required for pre-mRNA splicing. Binds GTP (1008 aa)

PRP6
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 (899 aa)
     
 
  0.953
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)

PSP2
Asn rich cytoplasmic protein that contains RGG motifs; high-copy suppressor of group II intron-splicing defects of a mutation in MRS2 and of a conditional mutation in POL1 (DNA polymerase alpha); possible role in mitochondrial mRNA splicing; DNA polymerase alpha mutation suppressor. Suppressor of group II intron splicing defects of a mutation in MRS2. May play a role in mitochondrial mRNA splicing (593 aa)

EFT1
Elongation factor 2 (EF-2), also encoded by EFT2; catalyzes ribosomal translocation during protein synthesis; contains diphthamide, the unique posttranslationally modified histidine residue specifically ADP-ribosylated by diphtheria toxin; Catalyzes the GTP-dependent ribosomal translocation step during translation elongation. During this step, the ribosome changes from the pre-translocational (PRE) to the post- translocational (POST) state as the newly formed A-site-bound peptidyl-tRNA and P-site-bound deacylated tRNA move to the P and E sites, respectively. Catalyzes the coordinated m [...] (842 aa)

GIS2
Translational activator for mRNAs with internal ribosome entry sites; associates with polysomes and binds to a specific subset of mRNAs; ortholog of human ZNF9/CNBP, a gene involved in myotonic dystrophy type 2; May act in the sexual differentiation pathway (153 aa)

BAS1
Myb-related transcription factor involved in regulating basal and induced expression of genes of the purine and histidine biosynthesis pathways; also involved in regulation of meiotic recombination at specific genes; Activates HIS4 transcription only in combination with PHO2/BAS2. BAS1 is also involved in the regulation of the purine biosynthesis pathway (811 aa)

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)

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).
