**Background of Human RHOT2 Protein**
RHOT2 (Ras Homolog Enriched in Brain-T2), also known as MIRO2. is a mitochondrial Rho GTPase encoded by the *RHOT2* gene. It belongs to the MIRO family of atypical GTPases, which are evolutionarily conserved and primarily localized to the outer mitochondrial membrane. RHOT2 plays a critical role in regulating mitochondrial dynamics, including motility, trafficking, and intracellular positioning. It interacts with microtubule-based motor proteins (e.g., kinesin and dynein) to coordinate mitochondrial movement along cytoskeletal networks, ensuring proper distribution of mitochondria to meet cellular energy demands.
Structurally, RHOT2 contains two GTPase domains (N-terminal and internal) and two calcium-binding EF-hand motifs, enabling it to act as a calcium sensor. This dual functionality links mitochondrial dynamics to cellular calcium signaling, particularly under stress conditions. Dysregulation of RHOT2 has been implicated in neurodegenerative disorders, such as Parkinson’s disease, due to impaired mitochondrial transport and homeostasis. Additionally, RHOT2 may influence apoptosis and metabolic adaptation in cancer cells.
Recent studies highlight its role in mitochondrial quality control via interactions with autophagy-related proteins. While RHOT2 shares functional overlap with its homolog RHOT1 (MIRO1), tissue-specific expression patterns and distinct regulatory mechanisms suggest divergent physiological roles. Ongoing research aims to elucidate RHOT2’s precise molecular mechanisms and therapeutic potential in mitochondrial-related pathologies.
