Nuclear receptor subfamily 2 group E member 1 (NR2E1)

Nuclear receptor subfamily 2 group E member 1 (NR2E1, also known as TLX) is an orphan nuclear receptor that functions primarily as a transcriptional repressor and regulator of gene expression in neural tissue. It plays a crucial role in maintaining the undifferentiated state and self-renewal capacity of adult neural stem cells, is essential for vision and proper retinal development, and helps pattern the anterior brain during embryogenesis. Dysregulation of NR2E1 disrupts neurogenesis, impairs vision, affects neural development, and can lead to behavioral abnormalities. Its activity appears to be modulated by specific ligands, including certain synthetic retinoids, and its molecular interactions—especially with corepressors—are structurally defined. NR2E1 is considered a high-value therapeutic target for diseases involving neural stem cell dysfunction or retinal pathology, though direct drug targeting remains in early research stages due to its role as an orphan nuclear receptor and the complexity of its functions
