Target Background

Function

Regulator of protein degradation that mediates the proteasomal targeting of misfolded, mislocalized or accumulated proteins. Acts by binding polyubiquitin chains of target proteins via its UBA domain and by interacting with subunits of the proteasome via its ubiquitin-like domain. Key regulator of DNA repair that represses homologous recombination repair: in response to DNA damage, recruited to sites of DNA damage following phosphorylation by ATM and acts by binding and removing ubiquitinated MRE11 from damaged chromatin, leading to MRE11 degradation by the proteasome. MRE11 degradation prevents homologous recombination repair, redirecting double-strand break repair toward non-homologous end joining (NHEJ). Specifically recognizes and binds mislocalized transmembrane-containing proteins and targets them to proteasomal degradation. Collaborates with DESI1/POST in the export of ubiquitinated proteins from the nucleus to the cytoplasm. Also plays a role in the regulation of the proteasomal degradation of non-ubiquitinated GJA1. Acts as an adapter protein that recruits UBQLN1 to the autophagy machinery. Mediates the association of UBQLN1 with autophagosomes and the autophagy-related protein LC3 (MAP1LC3A/B/C) and may assist in the maturation of autophagosomes to autolysosomes by mediating autophagosome-lysosome fusion.

UBQLN4 may induce cell cycle arrest and apoptosis via activation of the ERK pathway and upregulation of cyclin D1 in GES-1 cells. PMID: 29807370
results suggest that ubiquitinated proteins are exported from the nucleus to the cytosol in the UBIN-POST complex-dependent manner for the maintenance of nuclear protein homeostasis. PMID: 29666234
Here, the authors present a novel variant in UBQLN4 that is associated with ALS and show that its expression compromises motor axon morphogenesis in mouse motor neurons and in zebrafish. PMID: 28463112
UBQLN4, APP, CTNNB1, SHBG, and COL1A1 might be involved in the development of nonalcoholic fatty liver disease, and are proposed as the potential markers for predicting the development of this condition PMID: 28796060
UBQLN4 recognizes not only the defective model substrate but also a pool of endogenous defective proteins that were induced by the depletion of the SRP54 subunit of the signal recognition particle. PMID: 27113755
results suggested that CIP75 is essential for the interaction of Cx43 and the proteasome, but that alternate compensatory mechanisms exist to supplement the degradation normally facilitated by CIP75 PMID: 24256120
Targeting of Ubqln1 to autophagosomes requires the Ubqln4 UBL domain and the Ubqln1 UBA domain. PMID: 23459205
although CIP75 can interact with ubiquitinated cellular proteins, its interaction with Cx43 and stimulation of Cx43 proteasomal degradation does not require the ubiquitination of Cx43. PMID: 20940304
Co-immunoprecipitation confirmed the binding of small hydrophobic (SH) protein of mumps virus and ubiquilin 4 and demonstrates that a truncated protein fragment corresponding to amino acids 136-270 of ubiquilin 4 was sufficient for interaction. PMID: 20702650
A novel connexin43-interacting protein, CIP75, which belongs to the UbL-UBA protein family, regulates the turnover of connexin43 PMID: 18079109
