ARIH1 (Ariadne Homolog 1), also known as HHARI, is a member of the RING-between-RING (RBR) family of E3 ubiquitin-protein ligases. It plays a critical role in the ubiquitin-proteasome system by mediating the transfer of ubiquitin to specific substrate proteins, marking them for degradation or functional modification. Structurally, ARIH1 contains a conserved RBR domain that combines features of both RING and HECT-type E3 ligases, enabling a unique "hinge" mechanism to facilitate ubiquitination. Unlike canonical RING E3s, ARIH1 operates with E2 ubiquitin-conjugating enzymes (e.g., UBE2L3) to catalyze ubiquitin chain formation through a hybrid mechanism, often initiating priming steps in substrate modification.
Biologically, ARIH1 is implicated in diverse cellular processes, including protein quality control, DNA repair, innate immunity, and mitophagy. It interacts with Parkin, another RBR E3 ligase linked to Parkinson’s disease, to regulate mitochondrial homeostasis. Studies also highlight its role in targeting hypoxia-inducible factors (HIFs) and inflammatory signaling pathways (e.g., NF-κB). Dysregulation of ARIH1 is associated with cancer, neurodegenerative disorders, and immune dysfunctions. Its dual ability to function independently or synergistically with other E3 ligases makes it a key regulatory node in maintaining cellular proteostasis and stress responses. Research continues to explore its therapeutic potential in diseases linked to ubiquitination defects.
