{"type": "root", "children": [{"type": "p", "children": [{"type": "t", "text": "\nThe study investigated MYCN amplification in neuroblastoma and identified that the RNF121 wild‐type protein plays an essential oncogenic role by localizing predominantly to the cis‐Golgi complex and directly interacting with MYCN, thereby enhancing its stability. A point mutation in RNF121 (M158R), which disrupts Golgi localization and reduces protein stability, resulted in a pronounced decrease in tumorigenicity in MYCN‐amplified neuroblastoma models. This work underlines the importance of RNF121 as a cofactor that amplifies MYCN-driven oncogenic signaling, with its expression levels serving as a predictive marker for poor prognosis."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": ""}, {"type": "p", "children": [{"type": "t", "text": "\nFurther findings revealed that the RNF121-enhanced growth of neuroblastoma cells is particularly reliant on its transmembrane Helix 5, emphasizing the structural elements of RNF121 crucial for its role in stabilizing MYCN.
