DESCRIPTION

Also known as TNKS2_HUMAN, TNKS2, PARP5B, TANK2, TNKL. Poly-ADP-ribosyltransferase involved in various processes such as Wnt signaling pathway, telomere length and vesicle trafficking (PubMed:11739745, PubMed:11802774, PubMed:19759537, PubMed:21478859, PubMed:23622245, PubMed:25043379). 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 (PubMed:19759537, PubMed:21478859). Also mediates poly-ADP-ribosylation of BLZF1 and CASC3, followed by recruitment of RNF146 and subsequent ubiquitination (PubMed:21478859). Mediates poly-ADP-ribosylation of TERF1, thereby contributing to the regulation of telomere length (PubMed:11739745). Stimulates 26S proteasome activity (PubMed:23622245). Oligomerizes and associates with TNKS. Interacts with the cytoplasmic domain of LNPEP/Otase in SLC2A4/GLUT4-vesicles (PubMed:11802774). Binds to the N-terminus of Grb14 and TRF1 with its ankyrin repeat region (PubMed:11802774). Interacts with HIF1AN (PubMed:18936059, PubMed:21251231). Interacts with RNF146; this interaction leads to ubiquitination and proteasomal degradation (PubMed:21799911). Interacts with NUMA1 (PubMed:12080061).
