Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Phe282 of human aprataxin protein.
Background
Aprataxin is a DNA repair protein that resolves DNA lesions (DNA adenylates) caused by abortive ligations in single-strand break repair, double-strand break repair and base excision repair (1). Aprataxin is recruited to sites of DNA damage by PARP1 (2). In the mitochondria, aprataxin and tyrosyl-DNA-phosphodiesterase 1 (TDP1) are required for repair of single strand breaks caused primarily by reactive oxygen species (ROS) (3).
The gene for aprataxin, APTX, is defective in the neurodegenerative disorder oculomotor apraxia type 1 (AOA1)(4). Researchers have shown that levels of aprataxin can predict patient response to irinotecan-based treatments in colorectal cancer (5).
