Reticulon 2 (RTN2), a member of the reticulon protein family, is an endoplasmic reticulum (ER)-associated protein involved in membrane remodeling and lipid biosynthesis. This family is characterized by a conserved reticulon homology domain (RHD) with two hydrophobic regions that anchor the proteins to ER membranes. RTN2 shares structural features with other reticulons but exhibits tissue-specific expression patterns, particularly enriched in the nervous system. It exists as multiple isoforms generated by alternative splicing, which may contribute to functional diversity.
RTN2 plays roles in regulating ER morphology, vesicle trafficking, and neuronal differentiation. Studies suggest its involvement in modulating the tubular ER network and influencing membrane curvature through its RHD. Notably, RTN2 interacts with proteins linked to neurodegenerative diseases, including β-secretase (BACE1), affecting amyloid precursor protein processing. Dysregulation of RTN2 has been implicated in axonal degeneration, neuroinflammation, and pathologies like Alzheimer’s disease. Emerging research also explores its potential in autophagy and apoptosis regulation.
While RTN2's precise mechanisms remain under investigation, its conserved structural motifs and neurological prominence make it a focus for understanding ER-related cellular processes and neurodegeneration. Ongoing studies aim to clarify its isoform-specific functions and therapeutic potential.
