Summary: Predicted to enable K48-linked polyubiquitin modification-dependent protein binding activity and identical protein binding activity. Predicted to be involved in several processes, including negative regulation of double-strand break repair via homologous recombination; regulation of catabolic process; and ubiquitin-dependent protein catabolic process. Located in cytosol and endoplasmic reticulum membrane. Is expressed in several structures, including genitourinary system; heart; liver; lung; and spleen. Orthologous to human UBQLN4 (ubiquilin 4).

What's a GeneRIF?

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.
Title: UBQLN4 recognizes mislocalized transmembrane domain proteins and targets these to proteasomal degradation.
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.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
