Post Translational Modifications | Ubiquitinated at 'Lys-48' and 'Lys-63' by RNF146 when auto-poly-ADP-ribosylated.this leads to degradation. Deubiquitinated by USP25.leading to stabilization. ADP-ribosylated (-auto). Poly-ADP-ribosylated protein is recognized by RNF146, followed by ubiquitination. The crystallographic evidence suggests that the 3-hydroxyhistidine may be the (3S) stereoisomer. |
Function | 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. |
