MYEF2 is an RNA-binding protein and transcriptional regulator with pleiotropic functions across multiple biological contexts. In its canonical role, MYEF2 functions as a transcriptional repressor of myelin basic protein (MBP) by binding the proximal MB1 element in the MBP promoter [UniProt]. Beyond neural differentiation, MYEF2 exhibits broader significance in disease pathology and stress responses. MYEF2 associates with RNA granules, including stress granules and chr15-associated granules, and shares structural features with HNRNPM family proteins involved in epigenetic transmission and stress resistance 1. In cancer biology, MYEF2 shows context-dependent roles: elevated expression correlates with poor prognosis in hepatocellular carcinoma, where it promotes cell migration and invasion 2, yet in glioblastoma, high MYEF2 expression associates with better outcomes through negative correlation with CD8+ T cell exhaustion 3. MYEF2 participates in gene regulation through multiple mechanisms, including alternative splicing control 4, microRNA sponging pathways in breast cancer drug resistance 5, and regulation of Prader-Willi syndrome-related lncRNA processing 6. Additionally, MYEF2-derived lncRNA signatures show promise as non-invasive Alzheimer's disease biomarkers 7. These findings establish MYEF2 as a multifunctional regulator with potential clinical significance across neurological and malignant diseases.
