Anti-PARP1-S499-ADP-ribose antibody, clone AbD34251, recognizes PARP1, ADP-ribosylated at Serine 499. 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). PARP1/HPF1 during DNA damage response, primarily target PARP1 itself and histone H3, ribosylating these substrate proteins.

This anti-PARP1-S499-ADP-ribose antibody, clone AbD34251 was generated using an ADP-ribosylated PARP1S499 antigen. It is tagged with a SpyTag2 at the C-terminus of the Fab heavy chain, enabling the user to couple it to a SpyCatcher reagent for conversion to alternative formats in less than an hour. It has the same specificity than the human/rabbit IgG chimera antibody HCA356, clone AbD34251 that does not bind any of the other Ser-ADP-ribosylated peptides tested, nor does it bind poly-ADP-ribose in a site-specific manner (Bonfiglio et al. 2020).
