TRIM46. a member of the tripartite motif (TRIM) protein family, is characterized by its conserved RING finger, B-box, and coiled-coil domains, which are hallmark features of E3 ubiquitin ligases. Primarily expressed in neurons, TRIM46 plays a critical role in neurodevelopment and maintaining neuronal polarity. It localizes to the axon initial segment (AIS) and proximal axons, where it orchestrates the parallel microtubule organization essential for axonal transport and signal transmission. By stabilizing microtubule fascicles and regulating their density, TRIM46 ensures proper neuronal morphology and directional cargo trafficking. Its E3 ligase activity contributes to ubiquitination-mediated protein degradation or modification, potentially influencing pathways underlying synaptic plasticity and stress responses. Emerging studies link TRIM46 dysfunction to neurodevelopmental disorders and neurodegenerative diseases, such as Alzheimer's, where disrupted microtubule dynamics may exacerbate pathology. Despite progress, its substrate specificity, regulatory mechanisms, and broader roles in neural circuits remain under investigation, positioning TRIM46 as a compelling target for neurological research and therapeutic exploration.
