UniProtKB description: dsDNA-binding protein that contributes to the ionizing radiation resistance of D.radiodurans. Plays a role in DNA repair and genome reconstitution, and is necessary for recovery from severe genomic fragmentation as a result of exposure to severe levels of ionizing radiation. In vitro, binds to double-stranded DNA carrying strand breaks and stimulates the DNA end-joining reaction catalyzed by DNA ligases. Thus, PprA plays a critical role in a non-homologous end-joining (NHEJ) pathway for the repair of radiation-induced DNA double-strands breaks. Cannot bind to dsDNA without strand breaks or single-stranded DNA.
