STRINGSTRING
PPN1 protein (Saccharomyces cerevisiae) - STRING interaction network
"PPN1" - Vacuolar endopolyphosphatase with a role in phosphate metabolism 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

PPN1Vacuolar endopolyphosphatase with a role in phosphate metabolism; functions as a homodimer; Catalyzes the hydrolysis of inorganic polyphosphate (poly P) chains of many hundreds of phosphate residues into shorter lengths. The limited digestion products are 1 and 3 P(i) residues (674 aa)    
Predicted Functional Partners:
PPX1
Exopolyphosphatase, hydrolyzes inorganic polyphosphate (poly P) into Pi residues; located in the cytosol, plasma membrane, and mitochondrial matrix; Degradation of inorganic polyphosphates (397 aa)

NSR1
Nucleolar protein that binds nuclear localization sequences, required for pre-rRNA processing and ribosome biogenesis; Involved in pre-rRNA processing. Specifically binds nuclear localization sequences. Candidate for a receptor at the nucleus that may be involved in both RNA and protein transport. Binds telomeric sequences of the type (TG[1-3])n in vitro (414 aa)
       
      0.800
FPR2
Membrane-bound peptidyl-prolyl cis-trans isomerase (PPIase), binds to the drugs FK506 and rapamycin; expression pattern suggests possible involvement in ER protein trafficking; PPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides. FKBP-13 may play a role in protein trafficking in the ER (135 aa)

YAP1801
Protein involved in clathrin cage assembly; binds Pan1p and clathrin; homologous to Yap1802p, member of the AP180 protein family; Involved in endocytosis and clathrin cage assembly (637 aa)
       
 
  0.701
VTC2
Subunit of the vacuolar transporter chaperone (VTC) complex involved in membrane trafficking, vacuolar polyphosphate accumulation, microautophagy and non-autophagic vacuolar fusion; Component of the vacuolar transporter chaperone (VTC) complex, which plays a role in vacuolar membrane fusion (828 aa)
           
  0.680
SRP40
Nucleolar serine-rich protein; role in preribosome assembly or transport; may function as a chaperone of small nucleolar ribonucleoprotein particles (snoRNPs); immunologically and structurally to rat Nopp140; Not known; weak suppressor of a mutant of the subunit AC40 of DNA dependent RNA polymerase I and III (406 aa)

BSD2
Heavy metal ion homeostasis protein, facilitates trafficking of Smf1p and Smf2p metal transporters to the vacuole where they are degraded, controls metal ion transport, prevents metal hyperaccumulation, functions in copper detoxification; Required for homeostasis of heavy metal ions such as cadmium, cobalt and copper. Controls metal ion transport and prevents metal hyperaccumulation by negatively regulating the SMF1 and SMF2 metal transport systems. Under manganese-replete conditions facilitates trafficking of SMF1 and SMF2 metal transporters to the vacuole where they are degraded (321 aa)
           
  0.660
