STRINGSTRING
EST3 protein (Saccharomyces cerevisiae) - STRING interaction network
"EST3" - Component of the telomerase holoenzyme, involved in telomere replication 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

EST3Component of the telomerase holoenzyme, involved in telomere replication; Component of the telomerase complex involved in telomere replication. Stimulates RNA/DNA heteroduplex unwinding which favors the telomere replication by the telomerase (181 aa)    
Predicted Functional Partners:
EST2
Reverse transcriptase subunit of the telomerase holoenzyme, essential for telomerase core catalytic activity, involved in other aspects of telomerase assembly and function; mutations in human homolog are associated with aplastic anemia; Telomerase is a ribonucleoprotein enzyme essential for the replication of chromosome termini in most eukaryotes. It elongates telomeres. It is a reverse transcriptase that adds simple sequence repeats to chromosome ends by copying a template sequence within the RNA component of the enzyme (884 aa)
       
 
  0.956
EST1
TLC1 RNA-associated factor involved in telomere length regulation as recruitment subunit of telomerase; has G-quadruplex promoting activity that is required for telomere elongation; possible role in activating telomere-bound Est2p-TLC1-RNA; Directly involved in telomere replication. Associates with telomerase and during its interaction with CDC13, telomerase activity is promoted (699 aa)
       
 
  0.950
CDC13
Single stranded DNA-binding protein found at TG1-3 telomere G-tails; regulates telomere replication through recruitment of specific sub-complexes, but the essential function is telomere capping; Single-stranded telomeric DNA-binding protein that regulates telomere replication. Has a role in both positive and negative regulation. Promotes [TG(1-3)] strand lengthening via interaction with EST1. Promotes [C(1-3)A] strand re-synthesis by DNA polymerase alpha via interaction with POL1. Negatively regulates telomere elongation of the G strand via binding with STN1 thereby inhibiting telomera [...] (924 aa)

PRS4
5-phospho-ribosyl-1(alpha)-pyrophosphate synthetase, synthesizes PRPP, which is required for nucleotide, histidine, and tryptophan biosynthesis; one of five related enzymes, which are active as heteromultimeric complexes; 5-phosphoribose 1-diphosphate synthase involved in nucleotide, histidine, and tryptophan biosynthesis. Active in heteromultimeric complexes with other 5-phosphoribose 1- diphosphate synthases (PRS2, PRS3, PRS4 and PRS5) (326 aa)
       
      0.868
RAD52
Protein that stimulates strand exchange by facilitating Rad51p binding to single-stranded DNA; anneals complementary single-stranded DNA; involved in the repair of double-strand breaks in DNA during vegetative growth and meiosis; Involved in DNA double-strand break (DSB) repair and recombination. Promotes the annealing of complementary single- stranded DNA and by stimulation of the RAD51 recombinase (471 aa)
       
 
  0.812
NMD2
Protein involved in the nonsense-mediated mRNA decay (NMD) pathway; interacts with Nam7p and Upf3p; involved in telomere maintenance; Involved in nonsense-mediated decay of mRNAs containing premature stop codons. It interacts, via its C-terminus, with NAM7/UPF1. Could be involved in determining the efficiency of translational termination or reinitiation or factors involved in the initial assembly of an initiation- and termination-competent mRNP (1089 aa)
       
 
  0.779
STN1
Telomere end-binding and capping protein, plays a key role with Pol12p in linking telomerase action with completion of lagging strand synthesis, and in a regulatory step required for telomere capping; Has a role in telomere length regulation and telomere end protection. Acts as an inhibitor of telomerase loading through its interaction with CDC13 (494 aa)
           
  0.767
YKU70
Subunit of the telomeric Ku complex (Yku70p-Yku80p), involved in telomere length maintenance, structure and telomere position effect; relocates to sites of double-strand cleavage to promote nonhomologous end joining during DSB repair; Single-stranded DNA-dependent ATP-dependent helicase. Involved in non-homologous end joining (NHEJ) DNA double strand break repair. DNA-binding is sequence-independent but has a high affinity to nicks in double-stranded DNA and to the ends of duplex DNA. Binds to naturally occurring chromosomal ends, and therefore provides chromosomal end protection. Appe [...] (602 aa)
