DESCRIPTION

Also known as ASCC3_RAT, Ascc3. 3'-5' DNA helicase involved in repair of alkylated DNA. Promotes DNA unwinding to generate single-stranded substrate needed for ALKBH3, enabling ALKBH3 to process alkylated N3-methylcytosine (3mC) within double-stranded regions. Also involved in activation of the ribosome quality control (RQC) pathway, a pathway that degrades nascent peptide chains during problematic translation. Drives the splitting of stalled ribosomes, as part of the ribosome quality control trigger (RQT) complex. Part of the ASC-1 complex that enhances NF-kappa-B, SRF and AP1 transactivation. Identified in the ASCC complex that contains ASCC1, ASCC2 and ASCC3. Functions as scaffolding subunit that interacts directly with both ASCC1 and ASCC2. Interacts directly with ALKBH3, and thereby recruits ALKBH3 to the ASCC complex. Part of the ASC-1/TRIP4 complex, that contains TRIP4, ASCC1, ASCC2 and ASCC3. Identified in the RQT (ribosome quality control trigger) complex, that contains ASCC2, ASCC3 and TRIP4. Interacts with ASCC2. Interacts with TRIP4. Interacts with ZCCHC4. Interacts with ZNF598. Interacts with RPS3. Associates with ribosomes (By similarity).
