PARP3, Human (His, Strep)

The PARP3 protein is a mono-ADP ribosyltransferase that responds to DNA damage, focusing on mono-ADP ribosylation of proteins such as histone H2B, XRCC5, and XRCC6. PARP3 plays a key role in the DNA repair process, participating in precise nonhomologous end joining and inhibiting G-quadruplex structure. PARP3 Protein, Human (His, Strep) is the recombinant human-derived PARP3 protein, expressed by E. coli , with N-His, N-Strep II labeled tag.
