STRINGSTRING
STRING protein interaction network
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:
a 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 to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

UbqnUbiquilin, isoform A; Ubiquilin (Ubqn) encodes a protein containing an N-terminal ubiquitin-like domain and a C-terminal ubiquitin-associated domain. It binds and delivers ubiquitinated, misfolded or no longer functionally required proteins to the ubiquitin-proteasome system and/or autophagy. (547 aa)    
Predicted Functional Partners:
Rpn10
Regulatory particle non-ATPase 10 (Rpn10) encodes one of the polyubiquitin receptor subunits of the 26S proteasome. It recognizes and binds the polyubiquitin moiety of proteins intended for proteasomal degradation or the ubiquitin-like domain of extraproteasomal ubiquitin receptors.

Rpn11
26S proteasome non-ATPase regulatory subunit 14; Metalloprotease component of the 26S proteasome that specifically cleaves 'Lys-63'-linked polyubiquitin chains. The 26S proteasome is involved in the ATP-dependent degradation of ubiquitinated proteins. The function of the 'Lys-63'-specific deubiquitination of the proteasome is unclear (By similarity). Belongs to the peptidase M67A family. PSMD14 subfamily.

RpS27A
Ubiquitin-40S ribosomal protein S27a; Ubiquitin exists either covalently attached to another protein, or free (unanchored). When covalently bound, it is conjugated to target proteins via an isopeptide bond either as a monomer (monoubiquitin), a polymer linked via different Lys residues of the ubiquitin (polyubiquitin chains) or a linear polymer linked via the initiator Met of the ubiquitin (linear polyubiquitin chains). Polyubiquitin chains, when attached to a target protein, have different functions depending on the Lys residue of the ubiquitin that is linked: Lys-48-linked is involve [...]

CG31528
FI07626p; Polyubiquitin modification-dependent protein binding. It is involved in the biological process described with: ubiquitin-dependent protein catabolic process.

RpL40
Ubiquitin-60S ribosomal protein L40; [Ubiquitin]: exists either covalently attached to another protein, or free (unanchored). When covalently bound, it is conjugated to target proteins via an isopeptide bond either as a monomer (monoubiquitin), a polymer linked via different Lys residues of the ubiquitin (polyubiquitin chains) or a linear polymer linked via the initiator Met of the ubiquitin (linear polyubiquitin chains). Polyubiquitin chains, when attached to a target protein, have different functions depending on the Lys residue of the ubiquitin that is linked: Lys-48-linked is invol [...]

Rpn9
26S proteasome regulatory complex subunit p39A; Structural molecule activity. It is involved in the biological process described with: ubiquitin-dependent protein catabolic process; proteasome assembly; proteasome-mediated ubiquitin-dependent protein catabolic process.

Ubi-p63E
Polyubiquitin; Ubiquitin exists either covalently attached to another protein, or free (unanchored). When covalently bound, it is conjugated to target proteins via an isopeptide bond either as a monomer (monoubiquitin), a polymer linked via different Lys residues of the ubiquitin (polyubiquitin chains) or a linear polymer linked via the initiator Met of the ubiquitin (linear polyubiquitin chains). Polyubiquitin chains, when attached to a target protein, have different functions depending on the Lys residue of the ubiquitin that is linked: Lys-48-linked is involved in protein degradatio [...]

Rad23
DNA repair protein Rad23; Rad23 (Rad23) encodes an evolutionarily conserved member of the proteasome-associated proteins. It acts as a shuttle -or bridge- protein helping ubiquitinated proteins to interact with the proteasome, which in turn regulates their turnover.
    
 
 0.885
Psn
Presenilin homolog; Probable catalytic subunit of the gamma-secretase complex, an endoprotease complex that catalyzes the intramembrane cleavage of integral membrane proteins such as Notch receptor. Required for S3 cleavage of Notch, which releases activated Notch protein from the cell membrane. Involved in the patterning of the optic lobes. Belongs to the peptidase A22A family.

Rpt1
26S proteasome regulatory complex subunit p48B; Regulatory particle triple-A ATPase 1 (Rpt1) encodes an AAA-type ATPase protein that forms part of the heterohexameric ATPase ring of the regulatory complex of the 26S proteasome.
