Other Information

**Key Characteristics:** PEX3 is a hydrophobic protein that belongs to the PEX family of proteins, which are essential for peroxisomal biogenesis. It is characterized by a high degree of sequence similarity to other PEX proteins, including PEX1, PEX2, and PEX14. PEX3 is primarily expressed in cells of the nervous system, including neurons, and is also found in fibroblasts of cardiac tissue and adrenal gland cells. The protein is localized to the peroxisomal membrane and interacts with other PEX proteins to facilitate peroxisomal assembly and function. **Pathways and Functions:** PEX3 is involved in the following pathways: 1. **Abc-family proteins mediated transport:** PEX3 interacts with ABC transporter proteins to facilitate the transport of peroxisomal proteins across the peroxisomal membrane. 2. **Class i peroxisomal membrane protein import:** PEX3 is involved in the import of peroxisomal membrane proteins into the peroxisomal matrix. 3. **Protein binding and localization:** PEX3 binds to other PEX proteins and peroxisomal proteins, ensuring their proper localization to the peroxisomal membrane. 4. **Protein import into peroxisome membrane:** PEX3 plays a crucial role in the targeting of peroxisomal proteins to the peroxisomal membrane. **Functions:** PEX3 has several functions, including: 1. **Peroxisomal biogenesis:** PEX3 is essential for the assembly and targeting of peroxisomal proteins to the peroxisomal membrane. 2. **Fatty acid oxidation:** PEX3 is involved in the regulation of fatty acid oxidation, a critical process in energy metabolism. 3. **Detoxification:** PEX3 plays a role in the detoxification of harmful substances, such as bile acids and cholesterol. **Clinical Significance:** Dysregulation of PEX3 has been implicated in several neurodegenerative disorders, including: 1. **Peroxisomal biogenesis disorders (PBDs):** PEX3 mutations have been associated with PBDs, which are characterized by impaired peroxisomal function and accumulation of toxic substances. 2. **Neurodegenerative diseases:** PEX3 has been linked to neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, and Huntington's disease, where impaired peroxisomal function contributes to disease progression. 3. **Cancer:** PEX3 has been implicated in cancer development and progression, where impaired peroxisomal function can lead to the accumulation of toxic substances and the promotion of tumorigenesis. In conclusion, PEX3 is a critical protein involved in peroxisomal biogenesis and function. Its dysregulation has been implicated in several neurodegenerative disorders and cancer. Further research is needed to fully understand the role of PEX3 in human disease and to develop therapeutic strategies to target this protein.
