Description

This entry includes Ufd1 from fungi and Ufd1-like proteins from animals and plants.

Ufd1 is part of the Ufd1-Npl4 complex that functions as the substrate-recruiting cofactor for Cdc48 segregase. The Cdc48-Ufd1-Npl4 complex is involved in degradation of misfolded ER proteins [PMID: 20206597]. The Ufd1-Npl4 complex has been found to recruit Cdc48 to ubiquitylated CMG (Cdc45-MCM-GINS) helicase at the end of chromosome replication, thereby driving the disassembly reaction [PMID: 28355556].

In humans, Npl4-Ufd1 acts as a cofactor in reducing antiviral innate immune responses by facilitating proteasomal degradation of RIG-I (a viral RNA sensor) [PMID: 26471729].
