Other Information

**Key Characteristics:** POLR2I is a 73-kDa protein that is highly conserved across species. It is a subunit of the Pol II enzyme, which is responsible for transcribing approximately 80% of the human genome. POLR2I is responsible for the phosphorylation and interaction of the Pol II C-terminal domain (CTD) with other proteins, which is essential for transcription elongation and processivity. The protein also interacts with other transcription factors and co-factors to regulate gene expression. **Pathways and Functions:** POLR2I is involved in various cellular pathways, including: 1. **Transcription elongation:** POLR2I plays a crucial role in the phosphorylation and interaction of the Pol II CTD, which is essential for transcription elongation and processivity. 2. **Gene expression:** POLR2I regulates gene expression by interacting with transcription factors and co-factors, including the CTD, to control the recruitment of RNA polymerase II to promoters. 3. **DNA repair:** POLR2I is involved in the repair of DNA damage by interacting with other proteins to regulate the activity of DNA repair enzymes. 4. **Cell cycle regulation:** POLR2I is required for the regulation of the cell cycle by interacting with other proteins to control the expression of genes involved in cell proliferation and survival. 5. **Neurological disorders:** POLR2I has been implicated in the regulation of gene expression in the nervous system, and its dysregulation has been associated with neurological disorders, including Alzheimer's disease and schizophrenia. **Clinical Significance:** Dysregulation of POLR2I has been implicated in various diseases, including: 1. **Cancer:** POLR2I is often overexpressed in cancer cells, where it contributes to the regulation of gene expression and tumorigenesis. 2. **Neurological disorders:** POLR2I has been implicated in the regulation of gene expression in the nervous system, and its dysregulation has been associated with neurological disorders, including Alzheimer's disease and schizophrenia. 3. **Infectious diseases:** POLR2I has been implicated in the regulation of gene expression in response to viral infections, and its dysregulation has been associated with the progression of infectious diseases, including HIV-1 and influenza. 4. **Aging and longevity:** POLR2I has been implicated in the regulation of gene expression in response to cellular stress, and its dysregulation has been associated with aging and longevity. In conclusion, POLR2I is a critical regulator of transcription and beyond, with implications for various diseases, including cancer, neurological disorders, infectious diseases, and aging. Further research is needed to fully understand the mechanisms by which POLR2I regulates gene expression and its role in disease.
