About UBQLN4

Cytogenetic location: 1q22 Genomic coordinates (GRCh38): 1:156,031,247-156,053,798 (from NCBI)

This gene has 3 transcripts (splice variants), 235 orthologues and 5 paralogues. Ubiquitous expression in brain (RPKM 15.5), endometrium (RPKM 13.7) and 25 other tissues.

Summary

Enables K48-linked polyubiquitin modification-dependent protein binding activity and identical protein binding activity. Involved in cellular response to DNA damage stimulus; negative regulation of double-strand break repair via homologous recombination; and regulation of cellular catabolic process. Located in several cellular components, including autophagosome; nucleoplasm; and site of DNA damage. Part of protein-containing complex. Colocalizes with cytosolic Proteasome complex and nuclear Proteasome complex. [provided by Alliance of Genome Resources, Apr 2022]
