Summary

This gene encodes a protein that functions in the DNA double-strand break repair pathway choice, promoting non-homologous end joining (NHEJ) pathways, and limiting homologous recombination. This protein plays multiple roles in the DNA damage response, including promoting checkpoint signaling following DNA damage, acting as a scaffold for recruitment of DNA damage response proteins to damaged chromatin, and promoting NHEJ pathways by limiting end resection following a double-strand break. These roles are also important during V(D)J recombination, class switch recombination and at unprotected telomeres. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Aug 2017] CIViC Summary for TP53BP1 Gene

Forensic Context

A study in human keratinocytes and mouse skin demonstrated that X-ray irradiation (5 Gy) significantly downregulated the TP53BP1 gene (0.57-fold) alongside 58 other genes, while 16 genes were upregulated, as identified by cDNA microarray analysis [Koike et al. DOI:10.1269/jrr.46.173].
