Function

[TNKS2_HUMAN] Poly-ADP-ribosyltransferase involved in various processes such as Wnt signaling pathway, telomere length and vesicle trafficking. Acts as an activator of the Wnt signaling pathway by mediating poly-ADP-ribosylation of AXIN1 and AXIN2, 2 key components of the beta-catenin destruction complex: poly-ADP-ribosylated target proteins are recognized by RNF146, which mediates their ubiquitination and subsequent degradation. Also mediates poly-ADP-ribosylation of BLZF1 and CASC3, followed by recruitment of RNF146 and subsequent ubiquitination. Mediates poly-ADP-ribosylation of TERF1, thereby contributing to the regulation of telomere length. May also regulate vesicle trafficking and modulate the subcellular distribution of SLC2A4/GLUT4-vesicles.^[1] ^[2] ^[3] ^[4]

Publication Abstract from PubMed

Tankyrases (TNKS/TNKS2) belong to the poly(ADP-ribose) polymerase family. Inhibition of their enzymatic activities attenuates the Wnt/beta-catenin signaling, which plays an important role in cancer pathogenesis. We previously reported the discovery of RK-287107, a spiroindoline-based, highly selective, potent tankyrase inhibitor. Herein we describe the optimization process of RK-287107 leading to RK-582, which exhibits a markedly improved robust tumor growth inhibition in a COLO-320DM mouse xenograft model when orally administered. In addition to the dose-dependent elevation and attenuation of the levels of biomarkers AXIN2 and beta-catenin, respectively, results of the TCF reporter and cell proliferation studies on COLO-320DM are discussed.
