Protein Name: Activating signal cointegrator 1 complex subunit 3

UniprotKB/SwissProt ID: Q8N3C0 (Q8N3C0)

Gene Name: ASCC3

Organism: Homo sapiens (Human)

Function: ATPase involved both in DNA repair and rescue of stalled ribosomes (PubMed:22055184, PubMed:28757607, PubMed:32099016, PubMed:32579943, PubMed:36302773). 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 (PubMed:22055184). Also involved in activation of the ribosome quality control (RQC) pathway, a pathway that degrades nascent peptide chains during problematic translation (PubMed:28757607, PubMed:32099016, PubMed:32579943, PubMed:36302773). Drives the splitting of stalled ribosomes that are ubiquitinated in a ZNF598-dependent manner, as part of the ribosome quality control trigger (RQT) complex (PubMed:28757607, PubMed:32099016, PubMed:32579943, PubMed:36302773). Part of the ASC-1 complex that enhances NF-kappa-B, SRF and AP1 transactivation (PubMed:12077347)
