Anti-H3-S10-ADP-ribose antibody, clone AbD33644, recognizes Histone H3, ADP-ribosylated at Serine 10. This antibody also recognizes the less abundant H3 site H3-S28-ADP-ribose, however this is with a lower affinity and is due to the similarities between sequences flanking the two H3 target sites. This clone does not detect poly-ADP-ribose in a site-specific manner (Bonfiglio et al. 2020).

Poly(ADP-ribose) polymerase 1 (PARP1) is an early responder to DNA damage in human cells. Upon binding to genomic lesions PARP1 is able to transfer a mono- or poly-ADP-ribose residue from nicotinamide adenine dinucleotide (NAD+) to their substrate proteins, for chromatin decompaction and repair factor recruitment (Bütepage et al. 2015, Suskiewicz et al. 2020).

During the DNA damage response, serine is the primary target for PARP1 ADP-ribosylation which uses Histone PARylation factor 1 (HPF1) as an accessory factor to switch the amino-acid specificity of PARP1 from aspartate/glutamate to serine residues (Bonfiglio et al. 2017, Suskiewicz et al. 2020). During the DNA damage response PARP1 and HPF1 primarily target PARP1 itself and histone H3, ribosylating these targets.

This clone has been used in Western blotting, in the context of the DNA damage response with Histone H3 Ser-ADPr sites recognized by this antibody in lysates from Wild Type and ARH3 KO cells treated with H2O2 (Bonfiglio et al. 2020).
