背景信息

ART5 (ADP-ribosyltransferase 5), also known as PARP5 or TNKS, is a member of the poly-ADP-ribose polymerase (PARP) family, which plays critical roles in DNA repair, chromatin remodeling, and cellular signaling. Unlike classical PARPs involved in DNA damage response, ART5 primarily regulates Wnt/β-catenin signaling by modulating axin stability through ADP-ribosylation. This post-translational modification influences the assembly of the β-catenin destruction complex, thereby impacting embryonic development, stem cell maintenance, and tissue homeostasis.

Recombinant ART5 protein is engineered using expression systems like E. coli or mammalian cells to ensure proper folding and enzymatic activity. Its production enables biochemical studies, inhibitor screening for cancer therapy, and structural analyses (e.g., crystallography). ART5's unique ankyrin repeat and sterile alpha motif (SAM) domains facilitate protein-protein interactions, making it a target for disrupting oncogenic Wnt signaling in colorectal and other cancers.

Research on recombinant ART5 has advanced understanding of tankyrase-mediated PARylation mechanisms and spurred drug development, particularly PARP inhibitors aiming to exploit synthetic lethality in cancer cells. However, selectivity challenges persist due to structural similarities among PARP family members. Ongoing studies explore ART5's roles in telomere maintenance, glucose metabolism, and neurodegenerative diseases, highlighting its multifaceted biological significance.
