XRCC1
Introduction
XRCC1 is a vital protein in DNA repair, particularly for single-strand breaks caused by radiation and alkylating agents. It collaborates with DNA ligase III, polymerase β, and poly (ADP-ribose) polymerase in base excision repair. It might also play a role in meiosis-related DNA processes. Although XRCC1 lacks enzymatic activity, it acts as a scaffold for repair enzymes, aiding in single-strand break repair, base excision repair, and nucleotide excision repair[1]. XRCC1's structure includes three domains, enabling interactions with various repair proteins. Additionally, it is involved in error-prone microhomology-mediated end joining repair of double-strand breaks, often leading to mutation-inducing deletions.
Usage and Biology
We heterologously expressed codon-optimized XRCC1 in E. coli, endowing it with anti-UV capability.
