Potential relevance to the human ageing process

Main reason for selection: Entry selected based on evidence linking the gene product to a pathway or mechanism linked to ageing
Description: TP53BP1 is a DNA damage response protein that acts to preserve genomic integrity through the non-homologous end joining (NHEJ) pathway. BRCA1 mouse mutants result in embryonic lethality and hypomorphic BRCA1 mice and heterozygous for TP53 have slower growth rates and display signs of premature ageing [37]. These phenotypes are almost completely reverted in double knockout mice lacking TP53BP1. The mutant mice showed an almost normal lifespan and displayed a relative absence of various progeroid phenotypes, even though high levels of genomic instability were still observed [2186]. In humans, TP53BP1 has also been implicated in various forms of cancer [2191]. As TP53BP1 is involved in DNA damage responses, along with TP53, ATM and other ageing-associated players, and it might play a role during human ageing.
