The PADR1, known as the third zinc-binding domain (Zn3) localises between the N-terminal PARP-type zinc fingers (Zn1 and Zn2) and the central BRCT domain; it is involved in protein-protein interactions that orchestrate PARP-1 activation and are critical to the DNA-dependent stimulation of PARP-1 [1-5].

The PADR1 domain is involved in protein-protein interactions that orchestrate PARP-1 activation and are critical to the DNA-dependent stimulation of PARP-1. PADR1 consists of an N-terminal helical region, the central zinc ribbon fold and a C-terminal tail.
