MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a protein that belongs to a family of helicases that are involved in the ATP-dependent unwinding of nucleic acid duplexes. The encoded protein is the largest subunit of the activating signal cointegrator 1 complex that is involved in DNA repair and resistance to alkylation damage. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Sep 2013]

Protein Function and Prediction

ASCC3 is a ubiquitously expressed 3’-5’ superfamily II-type DNA helicase that generates single-stranded DNA (1;2). Once bound to the DNA, ASCC3 unwinds the DNA to generate a single-stranded DNA molecule that the dealkylating enzyme, ALKBH3, binds and functions (1).  ASCC3 is required to maintain genomic integrity and loss of ASCC3 leads to reduced cell proliferation of tumor cell lines that are dependent on the ASCC3-mediated mathway for alkylation damage resistance (1).
