Mitochondrial Rho GTPase 2 (RHOT2/MIRO2) is an outer mitochondrial membrane protein that serves as a critical regulator of mitochondrial trafficking, dynamics, and quality control. It is essential for neuronal survival and has been implicated in Parkinson's disease pathogenesis. [@nguyen2014]
Overview
RHOT2 (Ras Homolog Family Member T2) is a protein encoded by a gene located on chromosome 16p13.3. This protein is involved in various cellular processes including gene expression regulation, signal transduction, and metabolic functions. RHOT2 plays important roles in neuronal function and is implicated in neurodegenerative diseases. [@macaskill2009]
