STRINGSTRING
PBP2 protein (Saccharomyces cerevisiae) - STRING interaction network
"PBP2" - RNA binding protein with similarity to mammalian heterogeneous nuclear RNP K protein, involved in the regulation of telomere position effect and telomere length 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

PBP2RNA binding protein with similarity to mammalian heterogeneous nuclear RNP K protein, involved in the regulation of telomere position effect and telomere length (413 aa)    
Predicted Functional Partners:
SIM1
Protein of the SUN family (Sim1p, Uth1p, Nca3p, Sun4p) that may participate in DNA replication, promoter contains SCB regulation box at -300 bp indicating that expression may be cell cycle-regulated; Involved in the remodeling of the cell wall during the various phases of yeast culture development and under various environmental conditions. Required for the maintenance of the CLB5 kinase activity (476 aa)
           
  0.924
PBP4
Pbp1p binding protein, interacts strongly with Pab1p-binding protein 1 (Pbp1p) in the yeast two-hybrid system; also interacts with Lsm12p in a copurification assay (185 aa)
           
  0.922
PBP1
Component of glucose deprivation induced stress granules, involved in P-body-dependent granule assembly; similar to human ataxin-2; interacts with Pab1p to regulate mRNA polyadenylation; interacts with Mkt1p to regulate HO translation; Appears to promote proper polyadenylation. In the absence of PBP1, the 3’termini of pre-mRNAs are properly cleaved but lack full-length poly(A) tails. May act to repress the ability of PAB1 to negatively regulate polyadenylation. Negative regulator of poly(A) nuclease (PAN) activity (722 aa)
     
   
  0.900
PAB1
Poly(A) binding protein, part of the 3’-end RNA-processing complex, mediates interactions between the 5’ cap structure and the 3’ mRNA poly(A) tail, involved in control of poly(A) tail length, interacts with translation factor eIF-4G; Binds the poly(A) tail of mRNA. Appears to be an important mediator of the multiple roles of the poly(A) tail in mRNA biogenesis, stability and translation. In the nucleus, interacts with the nuclear cleavage factor IA (CFIA), which is required for both mRNA cleavage and polyadenylation. Is also required for efficient mRNA export to the cytoplasm. Acts in [...] (577 aa)
     
 
  0.779
URA2
Bifunctional carbamoylphosphate synthetase/aspartate transcarbamylase; catalyzes the first two enzymatic steps in the de novo biosynthesis of pyrimidines; both activities are subject to feedback inhibition by UTP; This protein is a "fusion" protein encoding three enzymatic activities of the pyrimidine pathway (GATase, CPSase, and ATCase) (2214 aa)
       
      0.757
NAB6
Putative RNA-binding protein; associates with mRNAs encoding cell wall proteins in high-throughput studies; deletion mutants display increased sensitivity to some cell wall disrupting agents; expression negatively regulated by cAMP; RNA-binding protein that associates with mRNAs encoding cell wall proteins (1134 aa)
     
 
  0.694
VPS64
Protein required for cytoplasm to vacuole targeting of proteins; forms a complex with Far3p and Far7p to Far11p involved in recovery from pheromone-induced cell cycle arrest; mutant has increased aneuploidy tolerance; Participates in the control of the reentry into the cell cycle following pheromone treatment. Involved in vacuolar protein sorting (604 aa)
       
      0.683
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)
       
      0.667
HEF3
Translational elongation factor EF-3; paralog of YEF3 and member of the ABC superfamily; stimulates EF-1 alpha-dependent binding of aminoacyl-tRNA by the ribosome; normally expressed in zinc deficient cells; Weakly expressed functional homolog of translation elongation factor 3A (YEF3), not required for survival. Can complement loss of YEF3 when expressed from the YEF3 or ADH1 promoters. Required for the ATP-dependent release of deacylated tRNA from the ribosomal E-site during protein biosynthesis. Stimulates the eEF1A-dependent binding of aminoacyl-tRNA to the ribosomal A-site, which [...] (1044 aa)
       
      0.663
YEF3
Translation elongation factor 3; contains two ABC cassettes; binds and hydrolyzes ATP; YEF3 has a paralog, HEF3, that arose from the whole genome duplication; Required for the ATP-dependent release of deacylated tRNA from the ribosomal E-site during protein biosynthesis. Stimulates the eEF1A-dependent binding of aminoacyl-tRNA to the ribosomal A-site, which has reduced affinity for tRNA as long as the E-site is occupied. Plays a role as a negative regulator of the GCN2 kinase activity; impairs GCN1-mediated GCN2 activation on ribosomes by reducing GCN1-ribosome affinity, and hence GCN2 [...] (1044 aa)
