STRINGSTRING
PEP1 protein (Saccharomyces cerevisiae) - STRING interaction network
"PEP1" - Type I transmembrane sorting receptor for multiple vacuolar hydrolases 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

PEP1Type I transmembrane sorting receptor for multiple vacuolar hydrolases; cycles between the late-Golgi and prevacuolar endosome-like compartments; Functions as a sorting receptor in the Golgi compartment required for the intracellular sorting and delivery of soluble vacuolar proteins, like carboxypeptidase Y (CPY) and proteinase A. May execute multiple rounds of sorting by cycling between the late Golgi and a prevacuolar endosome-like compartment. Binds the Golgi-modified P2 form of CPY, and this interaction is dependent on the presence of an intact CPY vacuolar protein sorting signal (1579 aa)    
Predicted Functional Partners:
VPS35
Endosomal subunit of membrane-associated retromer complex required for retrograde transport; receptor that recognizes retrieval signals on cargo proteins, forms subcomplex with Vps26p and Vps29p that selects cargo proteins for retrieval; Plays a role in vesicular protein sorting. Required for the endosome-to-Golgi retrieval of the vacuolar protein sorting receptor VPS10. Vacuolar carboxypeptidase Y (CPY) sorting is completely dependent on the presence of functional VPS35. The latter may play a role in the function, modification or packaging of a CPY-specific receptor complex. Component [...] (944 aa)

PEP8
Vacuolar protein sorting protein that forms part of the multimeric membrane-associated retromer complex along with Vps35p, Vps29p, Vps17p, and Vps5p; essential for endosome-to-Golgi retrograde protein transport; Plays a role in vesicular protein sorting. Required for the endosome-to-Golgi retrieval of the vacuolar protein sorting receptor VPS10. Component of the membrane-associated retromer complex which is essential in endosome-to-Golgi retrograde transport. The VPS29-VPS26-VPS35 subcomplex may be involved in cargo selection (379 aa)

PRC1
Vacuolar carboxypeptidase Y (proteinase C, CPY); broad-specificity C-terminal exopeptidase involved in non-specific protein degradation in the vacuole; member of the serine carboxypeptidase family; Involved in degradation of small peptides. Digests preferentially peptides containing an aliphatic or hydrophobic residue in P1’ position, as well as methionine, leucine or phenylalanine in P1 position of ester substrate (532 aa)

VPS29
Subunit of the membrane-associated retromer complex; endosomal protein; essential for endosome-to-Golgi retrograde transport; forms a subcomplex with Vps35p and Vps26p that selects cargo proteins for endosome-to-Golgi retrieval; Plays a role in vesicular protein sorting. Required for the endosome-to-Golgi retrieval of the vacuolar protein sorting receptor VPS10. Component of the membrane-associated retromer complex which is essential in endosome-to-Golgi retrograde transport. The VPS29-VPS26-VPS35 subcomplex may be involved in cargo selection (282 aa)

Endosomal protein that forms a complex with Hse1p; required for recycling Golgi proteins, forming lumenal membranes and sorting ubiquitinated proteins destined for degradation; has Ubiquitin Interaction Motifs which bind ubiquitin (Ubi4p); Component of the ESCRT-0 complex which is the sorting receptor for ubiquitinated cargo proteins at the multivesicular body (MVB) and recruits ESCRT-I to the MVB outer membrane. Controls exit from the prevacuolar compartment (PVC) in both the forward direction to the vacuole and the return to the Golgi. Allows VPS10 to return to the (trans-Golgi netwo [...] (622 aa)
