Poly (ADP-ribose) polymerase (PARP) is a family of proteins that, generally speaking, transfer ADP-ribose units from NAD+ onto target nuclear proteins, forming long branched Poly ADP-ribose (PAR) chains. PARPs play key signaling roles in apoptosis, DNA excision and repair, and chromatin structure. PARPs are also involved in transcriptional regulation of several signaling pathways, including genes involved in inflammation.

Some of the PARP proteins are known as tankyrases (PARP5A and 5B). In particular, tankyrases (TNKS) play a role in the maintenance of telomere length, sister telomere association, and mitotic spindle organization. Tankyrase 1 also destabilizes axin, thereby activating Wnt signaling and driving tumor cell proliferation. Thus, the PARPs, and particularly the TNKS have become important cancer drug targets. Further evidence for this comes from the fact that PARP is overexpressed in lung, ovarian, and breast cancer, and PARP inhibitors are showing dramatic therapeutic potential for breast and ovarian cancer in phase I and II clinical trials.

BPS is the only company to offer an extensive portfolio of PARP products as well as screening and profiling services.
