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

ubxn-3UBX domain-containing protein 3; Ubiquitin-binding protein which acts as an adapter for ATPase cdc-48.1 and/or cdc-48.2, conferring substrate specificity. Together with ubxn-1 and ubxn-2, plays a role in hermaphrodite spermatogenesis probably by promoting the degradation of sex determination terminal factor tra-1. During mitosis, ensures the degradation of DNA licensing factor cdt-1 and the disassembly of the DNA replication CMG helicase complex by promoting the dissociation from chromatin of several of its components including cdc-45 and sld-5. (613 aa)    
Predicted Functional Partners:
ufd-1
Ubiquitin fusion degradation protein 1 homolog; Functions at a post-ubiquitination step in the ubiquitin fusion degradation (UFD) pathway (By similarity). In association with npl-4.1 and/or npl-4.2 and ATPase cdc-48.1 and/or cdc-48.2, involved in the cytoplasmic elimination of misfolded proteins exported from the ER. This pathway, known as ERAD, prevents the activation of the unfolded protein response (UPR) caused by the accumulation of misfolded proteins in the ER. During S phase and in association with npl-4.1 and/or npl-4.2, cdc-48.1 and/or cdc-48.2 and ubxn-3, ensures the degradati [...]

cdc-48.1
Transitional endoplasmic reticulum ATPase homolog 1; ATP-dependent chaperone which probably uses the energy provided by ATP hydrolysis to generate mechanical force to unfold substrate proteins, disassemble protein complexes, and disaggregate protein aggregates. Can also prevent aggregation of unfolded proteins also in an ATP- independent manner. Targets polyubiquitinated proteins for proteasomal degradation by binding to 'Lys-48'-linked polyubiquitin chains. Involved in the cytoplasmic elimination of misfolded proteins exported from the ER. This pathway, known as ERAD, prevents the act [...]

ubxn-2
UBX domain-containing protein 2; Ubiquitin-binding protein which acts as an adapter for ATPase cdc-48.1 and/or cdc-48.2, conferring substrate specificity. Together with ubxn-2 and ubxn-3, plays a role in hermaphrodite spermatogenesis probably by promoting the degradation of sex determination terminal factor tra-1. Probably in association with ATPase cdc-48.1 or/and cdc-48.2, regulates the centrosomal levels of kinase air-1 levels during mitotic progression by promoting air-1 removal from centrosomes in prophase. Also, regulates spindle orientation in the one-cell embryo by controlling [...]

ubxn-1
UBX domain-containing protein 1; Ubiquitin-binding protein which acts as an adapter for ATPase cdc-48.1 and/or cdc-48.2, conferring substrate specificity. Together with ubxn-2 and ubxn-3, plays a role in hermaphrodite spermatogenesis probably by promoting the degradation of sex determination terminal factor tra-1.
   
 
 0.924
ubxn-6
UBX domain-containing protein 6; Probably acts as an adapter for ATPase cdc-48.1 and/or cdc- 48.2, conferring substrate specificity. Involved in the lysosomal clearance of cellular material in diet restricted conditions.
   
 
 0.921
npl-4.2
Nuclear protein localization protein 4 homolog 2; In association with ufd-1 and ATPase cdc-48.1 and/or cdc- 48.2, involved in the cytoplasmic elimination of misfolded proteins exported from the ER. This pathway, known as ERAD, prevents the activation of the unfolded protein response (UPR) caused by the accumulation of misfolded proteins in the ER. During S phase and in association with ufd-1, cdc-48.1 and/or cdc-48.2 and ubxn-3, ensures the degradation of DNA licensing factor cdt-1 after the initiation of DNA replication and thus the disassembly of the DNA replication CGM helicase comp [...]

cdc-48.2
Transitional endoplasmic reticulum ATPase homolog 2; ATP-dependent chaperone which probably uses the energy provided by ATP hydrolysis to generate mechanical force to unfold substrate proteins, disassemble protein complexes, and disaggregate protein aggregates. However, able to prevent aggregation of unfolded proteins also in an ATP-independent manner. Targets polyubiquitinated proteins for proteasomal degradation by binding to 'Lys-48'-linked polyubiquitin chains. Involved in the cytoplasmic elimination of misfolded proteins exported from the ER. This pathway, known as ERAD, prevents [...]

ulp-4
Ubiquitin-like protease 4; Protease required for deconjugation of smo-1 conjugates from target proteins which is necessary for cell cycle progression. Required for respiration and the maintenance of normal mitochondrial homeostasis.

ufd-3
Ubiquitin fusion degradation protein 3 homolog; Plays a role in protein ubiquitination, sorting and degradation through its association with cdc-48.1 and/or cdc-48.2.

mcm-7
DNA replication licensing factor MCM7; Acts as component of the mcm2-7 complex (mcm complex) which is the putative replicative helicase essential for 'once per cell cycle' DNA replication initiation and elongation in eukaryotic cells. The active ATPase sites in the mcm2-7 ring are formed through the interaction surfaces of two neighboring subunits such that a critical structure of a conserved arginine finger motif is provided in trans relative to the ATP-binding site of the Walker A box of the adjacent subunit. The six ATPase active sites, however, are likely to contribute differential [...]
