Parp3 Gene is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Poly(ADP-Ribose) Polymerase 3 (PARP3) is the third member of the PARP family involved in DNA repair and cell division. While PARP1 and PARP2 are well-characterized, PARP3 has emerged as an important regulator of DNA damage response and genomic stability.
