Other Information

**Key Characteristics:** EIF3H is a conserved subunit of the eukaryotic translation initiation complex, which is composed of multiple subunits. The protein is highly expressed in various cell types, including mesodermal cells, mature alpha-beta T cells, blood cells, and basal cells of prostate epithelium. EIF3H exhibits metal-dependent deubiquitinase activity and metallopeptidase activity, suggesting its role in regulating protein degradation and translation. Additionally, EIF3H is involved in the regulation of translational initiation, ribosomal scanning, and start codon recognition. **Pathways and Functions:** EIF3H is integral to several key pathways, including: 1. **Activation of mRNA upon binding of the cap-binding complex and eIFs**: EIF3H facilitates the interaction between the cap-binding complex and eIFs, leading to the activation of mRNA translation. 2. **Binding to 40S ribosomal subunit**: EIF3H binds to the 40S ribosomal subunit, forming the eIF3 complex, which is essential for the initiation of translation. 3. **Regulation of translational initiation**: EIF3H regulates the recruitment of ribosomal subunits to the mRNA and the initiation of translation. 4. **Regulation of proteasomal ubiquitin-dependent protein catabolism**: EIF3H is involved in the regulation of protein degradation through the ubiquitin-proteasome pathway. 5. **Metal-dependent deubiquitinase activity**: EIF3H exhibits metal-dependent deubiquitinase activity, which is essential for the regulation of protein degradation and translation. **Clinical Significance:** EIF3H's dysregulation has been implicated in various diseases, including: 1. **Ceruloplasmin expression regulation**: EIF3H is involved in the translational silencing of ceruloplasmin expression, which is a hallmark of Wilson's disease. 2. **Prostate cancer**: EIF3H is overexpressed in prostate cancer cells, suggesting its potential role in the development and progression of prostate cancer. 3. **Immune system disorders**: EIF3H is expressed in various immune cells, including T cells and B cells, and its dysregulation may contribute to immune system disorders, such as autoimmune diseases. In conclusion, EIF3H is a crucial component of the eukaryotic translation initiation complex, and its dysregulation has significant implications for various diseases. Further research is needed to fully understand the mechanisms underlying EIF3H's functions and to explore its potential as a therapeutic target for diseases associated with its dysregulation.
