Trim32 Gene is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
TRIM32 (Tripartite Motif Containing 32) encodes an E3 ubiquitin ligase that plays important roles in protein quality control, mitochondrial function, and neuronal survival. It is located on chromosome 9q33.1 and contains multiple protein-protein interaction domains including RING finger, B-box, and coiled-coil domains.

TRIM32 is a member of the tripartite motif (TRIM) family of proteins characterized by:
- RING finger domain: E3 ubiquitin ligase activity
- B-box domain: Protein-protein interactions
- Coiled-coil domain: Dimerization and subcellular localization
Key molecular functions include:
- Ubiquitination: Targets proteins for degradation via the ubiquitin-proteasome system
- Mitochondrial quality control: Helps maintain mitochondrial integrity
- Tumor suppression: Acts as a tumor suppressor in various cancers
- Neuronal survival: Protects neurons through multiple signaling pathways
- TRIM32 mutations cause BBS, a ciliopathy characterized by obesity, retinal dystrophy, polydactyly, and cognitive impairment
- The protein localizes to basal bodies of cilia
- TRIM32 expression is altered in AD brain tissue
- May play a role in ubiquitination of amyloid-beta and tau proteins
- Dysregulated in AD microglia
- Associated with mitochondrial dysfunction in PD models
- TRIM32 can ubiquitinate parkin substrates
- Altered expression in PD substantia nigra
- Potential role in TDP-43 proteinopathy
- May affect protein aggregate clearance
- Tumor suppressor function through p53-dependent pathways
- Deregulated in various cancers including glioma
TRIM32 is widely expressed in:
- Ubiquitin modulators to enhance pathological protein clearance
- Mitochondrial protective agents
- AAV-mediated TRIM32 delivery for BBS
- Targeting TRIM32-dependent pathways in neurodegeneration
- Trim32 knockout mice show retinal and mitochondrial abnormalities
- Drosophila models demonstrate neuronal dysfunction
