ART1 (ADP-ribosyltransferase 1) is a member of the ADP-ribosyltransferase family, enzymes that catalyze the transfer of ADP-ribose groups from NAD⁺ to target proteins—a post-translational modification known as ADP-ribosylation. This modification regulates diverse cellular processes, including DNA repair, signal transduction, and immune responses. ART1. specifically, is a glycosylphosphatidylinositol (GPI)-anchored ectoenzyme primarily expressed in immune cells, muscle tissues, and certain epithelial cells. It plays a role in modulating extracellular signaling by modifying cell surface proteins or secreted molecules, influencing cell-cell communication and inflammatory pathways.
Recombinant ART1 protein is engineered using biotechnological methods, often expressed in bacterial or mammalian systems to ensure proper folding and enzymatic activity. Its production enables detailed studies of its structure-function relationships, substrate specificity, and regulatory mechanisms. Researchers utilize recombinant ART1 to investigate its involvement in pathophysiological conditions, such as autoimmune diseases, fibrosis, and cancer. For instance, ART1-mediated ADP-ribosylation of cell surface receptors (e.g., integrins or chemokine receptors) can alter immune cell adhesion or migration, contributing to inflammatory disorders or tumor microenvironment modulation.
Recent studies highlight ART1's dual role in promoting tissue repair and exacerbating chronic inflammation, depending on context. Its recombinant form is also explored for therapeutic applications, including targeted enzyme therapies or as a tool for developing inhibitors to mitigate ART1-driven pathologies. By dissecting its molecular interactions, scientists aim to harness ART1's regulatory potential while addressing its pathological contributions, advancing both basic science and translational medicine.
