STRINGSTRING
PBP4 protein (Saccharomyces cerevisiae) - STRING interaction network
"PBP4" - Pbp1p binding protein, interacts strongly with Pab1p-binding protein 1 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

PBP4Pbp1p 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)    
Predicted Functional Partners:
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)
       
 
  0.984
LSM12
Protein of unknown function that may function in RNA processing; interacts with Pbp1p and Pbp4p and associates with ribosomes; contains an RNA-binding LSM domain and an AD domain; GFP-fusion protein is induced by the DNA-damaging agent MMS (187 aa)
       
 
  0.973
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
PBP2
RNA binding protein with similarity to mammalian heterogeneous nuclear RNP K protein, involved in the regulation of telomere position effect and telomere length (413 aa)
           
  0.922
SMB1
Core Sm protein Sm B; part of heteroheptameric complex (with Smd1p, Smd2p, Smd3p, Sme1p, Smx3p, and Smx2p) that is part of the spliceosomal U1, U2, U4, and U5 snRNPs; homolog of human Sm B and Sm B’; Involved in pre-mRNA splicing. Binds snRNA U1, U2, U4 and U5 which contain a highly conserved structural motif called the Sm binding site (196 aa)
       
      0.810
CRH1
Chitin transglycosylase; functions in the transfer of chitin to beta(1-6) and beta(1-3) glucans in the cell wall; similar and functionally redundant to Utr2; localizes to sites of polarized growth; expression induced by cell wall stress; Probable glycosidase that plays a role in cell wall architecture. Required for the transfer of chitin to 1,6-beta- glucan in the cell wall (507 aa)
           
  0.623
EDC3
Non-essential conserved protein of unknown function, plays a role in mRNA decapping by specifically affecting the function of the decapping enzyme Dcp1p; localizes to cytoplasmic mRNA processing bodies; Stimulates decapping of both stable and unstable mRNA during mRNA decay. Does not affect nonsense-mediated mRNA decay. Required for normal P-body assembly (551 aa)
       
 
  0.556
DHH1
Cytoplasmic DExD/H-box helicase, stimulates mRNA decapping; coordinates distinct steps in mRNA function and decay, interacts with both the decapping and deadenylase complexes, may have a role in mRNA export and translation; C-terminus of Dhh1p inter /.../ith Ngr1p and promotes POR1, but not EDC1 mRNA decay; ATP-dependent RNA helicase involved in mRNA turnover, and more specifically in mRNA decapping by activating the decapping enzyme DCP1 (PubMed-11780629, PubMed-12032091, PubMed-11696541, PubMed-12730603, PubMed-15703442. PubMed-15706350). Is involved in G1/S DNA-damage checkpoint rec [...] (506 aa)

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)

IGO1
Protein required for initiation of G0 program; prevents degradation of nutrient-regulated mRNAs via the 5’-3’ mRNA decay pathway; phosphorylated by Rim15p; GFP protein localizes to the cytoplasm and nucleus; similar to Igo2p; Required for TORC1 to properly control gene expression and chronological life span. Plays an essential role in initiation of the G0 program by preventing the degradation of specific nutrient-regulated mRNAs via the 5’-3’ mRNA decay pathway (168 aa)
