Supplementary information

UBR4 also known as p600 is a large protein with a molecular weight of approximately 600 kDa. It functions as an E3 ubiquitin ligase participating in the ubiquitin-proteasome system by tagging substrates for degradation. UBR4 is widely expressed in various tissues indicating its diverse functional impact throughout the body. It interacts with different proteins and contributes to many cellular processes influencing protein quality control and turnover.

Biological function summary

UBR4/p600 plays a role in cellular proliferation migration and adhesion. It is part of a complex involved in cytoskeleton organization and interacts with actin and microtubules. The protein supports cell shape and mechanical signaling especially during cellular differentiation and embryonic development. UBR4 also participates in autophagy contributing to cellular homeostasis and survival under stress conditions.

Pathways

UBR4/p600 is involved in the ubiquitin-mediated proteolysis pathway which regulates protein stability and activity. It is associated with the Wnt signaling pathway where it influences cell fate determination and tissue homeostasis. UBR4 interacts with other proteins like β-catenin and APC which are important in transmitting and modulating the Wnt signals affecting various developmental processes.

UBR4/p600 has been linked to neurodegenerative diseases like Alzheimer's disease and developmental disorders. Its aberrant regulation can impact protein degradation pathways contributing to protein aggregation and neuronal cell death. The protein is related to diseases through its interaction with tau a protein known to form pathological aggregates in Alzheimer’s. Additionally mutations in UBR4 have been associated with Joubert syndrome highlighting its role in cilia function and cerebellar development.

Target data

E3 ubiquitin-protein ligase involved in different protein quality control pathways in the cytoplasm (PubMed : 25582440, PubMed : 29033132, PubMed : 34893540, PubMed : 37891180, PubMed : 38030679, PubMed : 38182926, PubMed : 38297121). Component of the N-end rule pathway : ubiquitinates proteins bearing specific N-terminal residues that are destabilizing according to the N-end rule, leading to their degradation (PubMed : 34893540, PubMed : 37891180, PubMed : 38030679). Recognizes both type-1 and type-2 N-degrons, containing positively charged amino acids (Arg, Lys and His) and bulky and hydrophobic amino acids, respectively (PubMed : 38030679). Does not ubiquitinate proteins that are acetylated at the N-terminus (PubMed : 37891180). Together with UBR5, part of a cytoplasm protein quality control pathway that prevents protein aggregation by catalyzing assembly of heterotypic 'Lys-11'-/'Lys-48'-linked branched ubiquitin chains on aggregated proteins, leading to substrate recognition by the segregase p97/VCP and degradation by the proteasome : UBR4 probably synthesizes mixed chains containing multiple linkages, while UBR5 is likely branching multiple 'Lys-48'-linked chains of substrates initially modified (PubMed : 29033132). Together with KCMF1, part of a protein quality control pathway that catalyzes ubiquitination and degradation of proteins that have been oxidized in response to reactive oxygen species (ROS) : recognizes proteins with an Arg-CysO3(H) degron at the N-terminus, and mediates assembly of heterotypic 'Lys-63'-/'Lys-27'-linked branched ubiquitin chains on oxidized proteins, leading to their degradation by autophagy (PubMed : 34893540). Catalytic component of the SIFI complex, a multiprotein complex required to inhibit the mitochondrial stress response after a specific stress event has been resolved : ubiquitinates and degrades (1) components of the HRI-mediated signaling of the integrated stress response, such as DELE1 and EIF2AK1/HRI, as well as (2) unimported mitochondrial precursors (PubMed : 38297121). Within the SIFI complex, UBR4 initiates ubiquitin chain that are further elongated or branched by KCMF1 (PubMed : 38297121). Mediates ubiquitination of ACLY, leading to its subsequent degradation (PubMed : 23932781). Together with clathrin, forms meshwork structures involved in membrane morphogenesis and cytoskeletal organization (PubMed : 16214886).
