Recombinant Human Activating signal cointegrator 1 complex subunit 3 (ASCC3)

Uniprot Id

Q8N3C0

Target Species

Human

Target Name

ASCC3

Target Full Name

Activating signal cointegrator 1 complex subunit 3

Target Function

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.

Target Background

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.
