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. Stimulates 26S proteasome activity.

CTIF was identified as a novel PARylation target of the TNKS2 in the centrosomal region of cells, which plays a role in the distribution of the centrosomal satellites.PMID:29789535
Either tankyrase 1 or 2 is sufficient to maintain telomere length, but both are required to resolve telomere cohesion and maintain mitotic spindle integrity. Tankyrases are required for Notch2 to exit the plasma membrane and enter the nucleus to activate transcription.PMID:29263426
Finally, through functional validation, we uncovered a role for TNKS/2 in peroxisome homeostasis and determined that this function is independent of TNKS enzyme activities.PMID:28723574
Polymerization is required for Tankyrase to drive beta-catenin-dependent transcription. The polymeric state supports PARP activity and allows Tankyrase to effectively access destruction complexes through enabling avidity-dependent AXIN binding.PMID:27494558
