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

cdc-48.3ATPase family protein 2 homolog; ATP-dependent chaperone which uses the energy provided by ATP hydrolysis to generate mechanical force to disassemble protein complexes (By similarity). Required for various steps of embryonic mitosis including centrosome duplication, spindle assembly, ER dynamics and cell cycle progression. Regulates the stability and activity of kinase air-2, a component of the chromosomal passenger complex (CPC). Inhibits air-2 kinase activity from metaphase to late telophase and negatively regulates air-2 stability during mitotic exit. Controls ER transition into she [...] (724 aa)    
Predicted Functional Partners:
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.

npl-4.1
Nuclear protein localization protein 4 homolog 1; 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 [...]

ubxn-4
UBX domain-containing protein 4; Probably acts as an adapter for ATPase cdc-48.1 and/or cdc- 48.2, conferring substrate specificity. May play a role in the ER- associated protein degradation pathway (ERAD) possibly acting as a platform to recruit both ubql-1 and cdc-48.1 and/or cdc-48.2 to the ER during ERAD.

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.

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 [...]

R151.6
Derlin-2; May be required for the degradation process of some specific misfolded endoplasmic reticulum (ER) luminal proteins. Participates in the transfer of misfolded proteins from the ER to the cytosol, where they are destroyed by the proteasome in a ubiquitin-dependent manner. Its precise function remains unclear, but its ability to complement der1 mutations in C.cerevisiae, suggests a similar function in the degradation of ER misfolded proteins.
