FUNCTION: Plays a role in DNA damage repair as component of the ASCC complex. Recruits ASCC3 and ALKBH3 to sites of DNA damage by binding to polyubiquitinated proteins that have 'Lys-63'-linked polyubiquitin chains (PubMed:29144457). Part of the ASC-1 complex that enhances NF-kappa-B, SRF and AP1 tr...
FUNCTION: Plays a role in DNA damage repair as component of the ASCC complex. Recruits ASCC3 and ALKBH3 to sites of DNA damage by binding to polyubiquitinated proteins that have 'Lys-63'-linked polyubiquitin chains (PubMed:29144457). Part of the ASC-1 complex that enhances NF-kappa-B, SRF and AP1 transactivation (PubMed:12077347). Involved in activation of the ribosome quality control (RQC) pathway, a pathway that degrades nascent peptide chains during problematic translation (PubMed:32099016). As part of the ribosome quality control trigger (RQT) complex, recognizes ZNF598-dependent ubiquitination of stalled ribosomes (By similarity). {ECO:0000250|UniProtKB:P53137, ECO:0000269|PubMed:12077347, ECO:0000269|PubMed:29144457, ECO:0000269|PubMed:32099016}.
