The protein encoded by this gene belongs to the PARP family. These enzymes modify nuclear proteins by poly-ADP-ribosylation, which is required for DNA repair, regulation of apoptosis, and maintenance of genomic stability. This gene encodes the poly(ADP-ribosyl)transferase 3, which is preferentially localized to the daughter centriole throughout the cell cycle. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]
Forensic Context
A review of human multi-omics studies for biological age estimation, which synthesizes findings from numerous cited investigations, identifies the PARP3 as a gene whose expression is positively associated with aging in whole blood samples from a cohort of healthy people [Solovev et al.
