TNKS2 (Tankyrase 2) is a Protein Coding gene. Among its related pathways are phosphorylation site mutants of CTNNB1 are not targeted to the proteasome by the destruction complex and HIV Life Cycle. GO annotations related to this gene include enzyme binding and NAD+ ADP-ribosyltransferase activity. An important paralog of this gene is TNKS. 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. Stimulates 26S proteasome activity.
