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

ufd-1Ubiquitin 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 [...] (342 aa)

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 [...]

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.

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 [...]

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 [...]

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.

ufd-2
Ubiquitin conjugation factor E4 ufd-2; Acts as an E4 ubiquitin ligase mediating the assembly of polyubiquitin chains on substrates ubiquitinated by another E3 ubiquitin ligase. The elongation of preexisting ubiquitin chains preferentially targets ubiquitin 'Lys-29' and 'Lys-48' residues. Also functions as an E3 ligase in conjunction with specific E1 and E2 ligases. Probably by regulating protein ubiquitination at DNA damage repair sites, coordinates DNA double- strand-break repair and apoptosis in the germline. Required for germline apoptosis in response to DNA damage downstream of cep [...]

cup-2
Derlin-1; Specifically required for the degradation process of 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. Belongs to the derlin family.

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.

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 [...]

UBX 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.
