E3 ubiquitin-protein ligase listerin

1610 amino acids

E3 ubiquitin-protein ligase component of the ribosome quality control complex (RQC), a ribosome-associated complex that mediates ubiquitination and extraction of incompletely synthesized nascent chains for proteasomal degradation. Ubiquitination leads to cdc48 recruitment for extraction and degradation of the incomplete translation product.

Belongs to the LTN1 family.

E3 ubiquitin-protein ligase listerin

1562 amino acids

E3 ubiquitin-protein ligase component of the ribosome quality control complex (RQC), a ribosome-associated complex that mediates ubiquitination and extraction of incompletely synthesized nascent chains for proteasomal degradation (PubMed:23178123). Mediates ubiquitination of proteins derived from mRNAs lacking stop codons (non-stop proteins) and other translation arrest products induced by poly-lysine sequences and tandem rare codons. Ubiquitination leads to CDC48 recruitment for extraction and degradation of the incomplete translation product (PubMed:20835226, PubMed:23825054, PubMed:24261871). May indirectly play a role in chromatin function and transcription (PubMed:17283062).

Belongs to the LTN1 family.
