Other Information

**Key Characteristics:** U2AF2 is a small nuclear RNA-binding protein that belongs to the C2H2 zinc finger domain family. It is characterized by its ability to bind to specific RNA sequences, particularly those containing the poly-pyrimidine tract (PPT) motif. U2AF2 is a multifunctional protein that interacts with various components of the spliceosome complex, including the U2 small nuclear RNA (snRNA) and the U2AF complex. Its expression is tissue-specific, with high levels observed in cells involved in hematopoiesis, such as B cells and plasmablasts. **Pathways and Functions:** U2AF2 is involved in several key pathways and functions, including: 1. **RNA Splicing:** U2AF2 plays a crucial role in the regulation of RNA splicing, specifically in the removal of introns and the joining of exons. It binds to the U2 snRNA and recruits the U2AF complex to the splice site, facilitating the splicing reaction. 2. **Spliceosome Assembly:** U2AF2 is a key component of the U2AF complex, which is essential for the assembly of the spliceosome complex. It interacts with other spliceosomal proteins to form a functional complex. 3. **Negative Regulation of RNA Splicing:** U2AF2 acts as a negative regulator of RNA splicing, inhibiting the splicing reaction by binding to the U2 snRNA and preventing the recruitment of the U2AF complex. 4. **Positive Regulation of RNA Splicing:** U2AF2 also acts as a positive regulator of RNA splicing, facilitating the splicing reaction by binding to the U2 snRNA and promoting the recruitment of the U2AF complex. **Clinical Significance:** Dysregulation of U2AF2 has been implicated in various diseases, including: 1. **Cancer:** U2AF2 mutations have been identified in several types of cancer, including breast cancer, lung cancer, and leukemia. These mutations can lead to the overexpression of U2AF2, resulting in aberrant RNA splicing and the production of aberrant proteins. 2. **Neurodegenerative Disorders:** U2AF2 has been implicated in neurodegenerative disorders, including amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Mutations in the U2AF2 gene have been identified in patients with these disorders, suggesting a role for U2AF2 in the regulation of RNA splicing and the production of aberrant proteins. 3. **Immune System Dysregulation:** U2AF2 is also involved in the regulation of immune responses, and dysregulation of U2AF2 has been implicated in immune system dysregulation, including autoimmune disorders and immunodeficiency diseases. In conclusion, U2AF2 is a critical gene that plays a pivotal role in the regulation of RNA splicing. Its dysregulation has been implicated in various diseases, including cancer, neurodegenerative disorders, and immune system dysregulation. Further research is needed to fully understand the mechanisms by which U2AF2 regulates RNA splicing and the implications of its dysregulation in human disease.
