STRINGSTRING
PSP2 protein (Saccharomyces cerevisiae) - STRING interaction network
"PSP2" - Asn rich cytoplasmic protein that contains RGG motifs 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

PSP2Asn 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)    
Predicted Functional Partners:
POL1
Catalytic subunit of the DNA polymerase I alpha-primase complex, required for the initiation of DNA replication during mitotic DNA synthesis and premeiotic DNA synthesis; Catalytic component of DNA polymerase alpha, which in complex with DNA primase (DNA polymerase alpha-primase) consitutes a replicative polymerase. POL1 has a role in promoting telomere replication during interaction with CDC13 (1468 aa)
       
 
  0.934
DBP1
Putative 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)
       
      0.868
POL32
Third subunit of DNA polymerase delta, involved in chromosomal DNA replication; required for error-prone DNA synthesis in the presence of DNA damage and processivity; interacts with Hys2p, PCNA (Pol30p), and Pol1p; DNA polymerase delta (DNA polymerase III) participates in chromosomal DNA replication. It is required during synthesis of the leading and lagging DNA strands at the replication fork and binds at/or near replication origins and moves along DNA with the replication fork. It has 3’-5’ proofreading exonuclease activity that correct errors arising during DNA replication. It is al [...] (350 aa)
           
  0.829
RAD24
Checkpoint protein, involved in the activation of the DNA damage and meiotic pachytene checkpoints; subunit of a clamp loader that loads Rad17p-Mec3p-Ddc1p onto DNA; homolog of human and S. pombe Rad17 protein; Participates in checkpoint pathways arrest of the cell cycle, a mechanism that allows the DNA repair pathways to act to restore the integrity of the DNA prior to DNA synthesis or separation of the replicated chromosomes. Regulates the DNA damage checkpoint pathway throughout the cell cycle, when associated with RCF5. Component of the RFC-like RAD24-RFC complex which loads the ch [...] (659 aa)
           
  0.829
PSP1
Asn and gln rich protein of unknown function; high-copy suppressor of POL1 (DNA polymerase alpha) and partial suppressor of CDC2 (polymerase delta) and CDC6 (pre-RC loading factor) mutations; overexpression results in growth inhibition; DNA polymerase alpha mutation suppressor (841 aa)
           
  0.829
DED1
ATP-dependent DEAD (Asp-Glu-Ala-Asp)-box RNA helicase, required for translation initiation of all yeast mRNAs; mutations in human DEAD-box DBY are a frequent cause of male infertility; 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. Has weak ATP-dependent affinity for dsRNA, but strong ATP- dependent affinity for ssRNA. Acts as a virus host factor involved in the replication of the MBV and the L-A viruses by promoting the negative-strand RNA synthesis. May [...] (604 aa)
       
      0.806
HMT1
Nuclear SAM-dependent mono- and asymmetric arginine dimethylating methyltransferase that modifies hnRNPs, including Npl3p and Hrp1p, affecting their activity and nuclear export; methylates U1 snRNP protein Snp1p and ribosomal protein Rps2p; S-adenosyl-L-methionine-dependent protein-arginine N- methyltransferase that catalyzes both the mono- and asymmetric (type I) dimethylation of the guanidino nitrogens of arginine residues in a variety of RNA-binding proteins such as heterogeneous nuclear ribonucleoproteins (hnRNPs) and small nuclear ribonucleoproteins (snRNPs) (PubMed-8668183, PubMe [...] (348 aa)
       
      0.782
CDC33
Cytoplasmic mRNA cap binding protein and translation initiation factor eIF4E; the eIF4E-cap complex is responsible for mediating cap-dependent mRNA translation via interactions with translation initiation factor eIF4G (Tif4631p or Tif4632p); Recognizes and binds the 7-methylguanosine-containing mRNA cap during an early step in the initiation of protein synthesis and facilitates ribosome binding by inducing the unwinding of the mRNAs secondary structures (213 aa)
       
      0.697
CDC6
Essential ATP-binding protein required for DNA replication, component of the pre-replicative complex (pre-RC) which requires ORC to associate with chromatin and is in turn required for Mcm2-7p DNA association; homologous to S. pombe Cdc18p; Plays a crucial role in forming the pre-replicative complexes. Interacts with the origin recognition complex (ORC) and MCM2-7 helicase complex leading to the linking of those complexes and loading of the replicative helicase MCM2-7 onto the pre- replicative complexes. Required for the initiation of DNA replication and then actively participates in t [...] (513 aa)

POL3
Catalytic subunit of DNA polymerase delta; required for chromosomal DNA replication during mitosis and meiosis, intragenic recombination, repair of double strand DNA breaks, and DNA replication during nucleotide excision repair (NER); DNA polymerase delta (DNA polymerase III) participates in chromosomal DNA replication.
