STRING protein interaction network
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 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
protein homology

Gene Fusion
prcAProteasome (alpha subunit) prca; Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation (267 aa)    
Predicted Functional Partners:
Proteasome (beta subunit) prcb; Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation
Transitional endoplasmic reticulum atpase; Belongs to the AAA ATPase family
Conserved hypothetical protein; Catalyzes the covalent attachment of the prokaryotic ubiquitin-like protein modifier Pup to the proteasomal substrate proteins, thereby targeting them for proteasomal degradation. This tagging system is termed pupylation. The ligation reaction involves the side-chain carboxylate of the C-terminal glutamate of Pup and the side- chain amino group of a substrate lysine
Proteasome-associated atpase; ATPase which is responsible for recognizing, binding, unfolding and translocation of pupylated proteins into the bacterial 20S proteasome core particle. May be essential for opening the gate of the 20S proteasome via an interaction with its C-terminus, thereby allowing substrate entry and access to the site of proteolysis. Thus, the C-termini of the proteasomal ATPase may function like a 'key in a lock' to induce gate opening and therefore regulate proteolysis
Prokaryotic ubiquitin-like protein pup; Protein modifier that is covalently attached to lysine residues of substrate proteins, thereby targeting them for proteasomal degradation. The tagging system is termed pupylation
Pup amidohydrolase; Conserved protein; Also detected in the membrane fraction by proteomics (2D-LC-MS/MS); cytoplasmic protein
Conserved protein; Cytoplasmic protein
Proteasome accessory factor b; Conserved protein; Detected in the cytoplasmic fraction by 2D-LC- MS/MS; cytoplasmic protein; contains domain homology to transcriptional regulators
Glycerol kinase glpk; Key enzyme in the regulation of glycerol uptake and metabolism. Catalyzes the phosphorylation of glycerol to yield sn- glycerol 3-phosphate
[cyso sulfur-carrier protein]-s-l-cysteine hydrolase; Conserved hypothetical protease; Cytoplasmic protein; function unknown but domain identity suggests this CDS encodes a metal-dependent protease of the Pad1/Jab1 superfamily
