STRINGSTRING
PEX5 protein (Saccharomyces cerevisiae) - STRING interaction network
"PEX5" - Peroxisomal membrane signal receptor for the C-terminal tripeptide signal sequence 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

PEX5Peroxisomal membrane signal receptor for the C-terminal tripeptide signal sequence (PTS1) of peroxisomal matrix proteins, required for peroxisomal matrix protein import; also proposed to have PTS1-receptor independent functions; Binds to the C-terminal PTS1-type tripeptide peroxisomal targeting signal (SKL-type) and plays an essential role in peroxisomal protein import (612 aa)    
Predicted Functional Partners:
PEX14
Peroxisomal membrane peroxin that is a central component of the peroxisomal protein import machinery; interacts with both PTS1 (Pex5p) and PTS2 (Pex7p), peroxisomal matrix protein signal recognition factors and membrane receptor Pex13p; Component of the peroxisomal translocation machinery with PEX13 and PEX17. Interacts with both the PTS1 and PTS2 receptors. Binds directly to PEX17 (341 aa)
     
  0.999
PEX13
Integral peroxisomal membrane protein required for translocation of peroxisomal matrix proteins, interacts with the PTS1 signal recognition factor Pex5p and the PTS2 signal recognition factor Pex7p, forms a complex with Pex14p and Pex17p; Component of the peroxisomal translocation machinery with PEX14 and PEX17. Interacts with the PTS1 receptor (PAS10/PEX5) (386 aa)
     
  0.999
PEX12
C3HC4-type RING-finger peroxin and E3 ubiquitin ligase, required for peroxisome biogenesis and peroxisomal matrix protein import; forms translocation subcomplex with Pex2p and Pex10p; mutations in human homolog cause peroxisomal disorder; Required for protein import into peroxisomes (399 aa)
     
  0.999
PEX7
Peroxisomal signal receptor for the N-terminal nonapeptide signal (PTS2) of peroxisomal matrix proteins; WD repeat protein; defects in human homolog cause lethal rhizomelic chondrodysplasia punctata (RCDP); Binds to the N-terminal PTS2-type peroxisomal targeting signal and plays an essential role in peroxisomal protein import essential for import of 3-oxoacyl-CoA thiolase (a PTS2-containing protein) into peroxisomes. May direct thiolase to peroxisomes by shuttling between the cytosol and peroxisomal membranes (375 aa)
     
  0.999
PEX10
Peroxisomal membrane E3 ubiquitin ligase, required for for Ubc4p-dependent Pex5p ubiquitination and peroxisomal matrix protein import; contains zinc-binding RING domain; mutations in human homolog cause various peroxisomal disorders; Somewhat implicated in the biogenesis of peroxisomes (337 aa)
     
  0.998
PEX11
Peroxisomal membrane protein required for medium-chain fatty acid oxidation and peroxisome proliferation, possibly by inducing membrane curvature; localization regulated by phosphorylation; transcription regulated by Adr1p and Pip2p-Oaf1p; Involved in peroxisomal proliferation. Promotes peroxisome division and biogenesis (236 aa)
     
  0.998
PEX17
Membrane peroxin of the peroxisomal importomer complex; complex facilitates the import of peroxisomal matrix proteins; required for peroxisome biogenesis; Component of the peroxisomal translocation machinery with PEX13 and PEX14. Interacts indirectly with the PTS1 receptor (PAS10/PEX5) and directly binds to PEX14. Required for import of both PTS1 and PTS2 proteins (199 aa)
       
  0.998
PEX2
RING-finger peroxin and E3 ubiquitin ligase, peroxisomal membrane protein with a C-terminal zinc-binding RING domain, forms translocation subcomplex with Pex10p and Pex12p which functions in peroxisomal matrix protein import; Required for the import of several proteins into peroxisomes (271 aa)
     
  0.997
PEX8
Intraperoxisomal organizer of the peroxisomal import machinery, tightly associated with the lumenal face of the peroxisomal membrane, essential for peroxisome biogenesis, binds PTS1-signal receptor Pex5p; Required for peroxisome assembly (589 aa)
       
  0.997
PEX19
Chaperone and import receptor for newly-synthesized class I peroxisomal membrane proteins (PMPs), binds PMPs in the cytoplasm and delivers them to the peroxisome for subsequent insertion into the peroxisomal membrane; Required for proper post-translational import and stabilization of peroxisomal membrane proteins (PMPs). Acts as a cytosolic import receptor for PMPs and delivers them to the docking factor PEX3 at the peroxisomal membrane for subsequent insertion into the membrane. Acts as a chaperone in stabilizing or maintaining PMPs in the lipid bilayer. Directs PEX17, a peripheral co [...] (342 aa)
