MTCH2 (Mitochondrial Carrier Homolog 2), also known as mitochondrial carrier 2 or SYNDI, is a member of the mitochondrial carrier family (SLC25A family) that functions as an outer mitochondrial membrane protein involved in metabolite transport, apoptosis regulation, and mitochondrial dynamics [1]. MTCH2 plays critical roles in neuronal survival and has been implicated in neurodegenerative diseases including Alzheimer's Disease and Parkinson's Disease.

MTCH2 is a phylogenetically conserved protein that localizes to the outer mitochondrial membrane. It belongs to the mitochondrial carrier family but exhibits unique structural and functional features that distinguish it from other family members. The protein plays multifaceted roles in mitochondrial biology, including metabolite transport, apoptosis regulation, mitophagy, and lipid metabolism [2].
In the nervous system, MTCH2 is essential for maintaining neuronal viability. It influences mitochondrial function in neurons through multiple mechanisms, and its dysregulation has been linked to neurodegenerative processes in both Alzheimer's Disease and Parkinson's Disease.
MTCH2 functions as a mitochondrial carrier with several key activities:
Unlike classic mitochondrial carriers that traverse the inner membrane, MTCH2 localizes to the outer mitochondrial membrane where it:
MTCH2 is intimately involved in mitochondrial-mediated apoptosis pathways:
MTCH2 is implicated in AD pathogenesis:
In PD, MTCH2 plays several roles:
MTCH2 dysregulation contributes to:
MTCH2 expression is altered in various cancers:
MTCH2 is ubiquitously expressed with high levels in:
In the brain, MTCH2 shows:
MTCH2 expression is regulated by:
MTCH2 is a potential therapeutic target:
MTCH2 may serve as:
