Background: FAF1, which has multiple ubiquitin-like domains, interacts with various proteins (VCP, Hsp70, and polyubiquitinated proteins). Results: Association of FAF1 UBX with VCP-Npl4-Ufd1 complex regulates ubiquitin binding to FAF1 UBA domain and promotes CD3 degradation in ERAD. Conclusion: FAF1 is a ubiquitin receptor that promotes ERAD by delivering polyubiquitinated proteins from UBX domain to UBA domain. Significance: FAF1 plays a role in ERAD by modulating domain-domain interaction.
