Other Information

**Key Characteristics:** 1. **Structural Composition:** RPA3 is a 14-kDa subunit of the RPA complex, composed of three subunits: RPA1, RPA2, and RPA3. 2. **Function:** RPA3 is involved in DNA replication, repair, and transcriptional regulation. 3. **Cellular Localization:** RPA3 is primarily found in the nucleus, where it plays a critical role in maintaining genome stability. 4. **Expression:** RPA3 is significantly expressed in various cell types, including erythroid progenitor cells, extravillous trophoblasts, and kidney collecting duct intercalated cells. **Pathways and Functions:** 1. **DNA Replication:** RPA3 plays a crucial role in unwinding DNA, binding ssDNA, and facilitating the assembly of the pre-replicative complex. 2. **DNA Damage Response:** RPA3 is involved in the activation of the ATR pathway in response to replication stress, as well as the regulation of cell cycle checkpoints. 3. **Transcriptional Regulation:** RPA3 interacts with transcription factors, such as TP53, to regulate gene expression. 4. **Cell Cycle Regulation:** RPA3 is involved in the regulation of the cell cycle, including the G1/S transition and the G2/M checkpoint. 5. **Base Excision Repair:** RPA3 is involved in the base excision repair pathway, which repairs damaged DNA bases. **Clinical Significance:** 1. **Cancer:** Dysregulation of RPA3 has been linked to various cancers, including breast, ovarian, and colon cancer. 2. **Fanconi Anemia:** RPA3 is a key component of the Fanconi anemia pathway, which is involved in the repair of interstrand DNA crosslinks. 3. **Genome Instability:** RPA3 dysregulation has been implicated in genome instability, which is a hallmark of many cancers. 4. **Neurological Disorders:** RPA3 has been implicated in various neurological disorders, including Alzheimer's disease and Parkinson's disease. In conclusion, RPA3 is a multifaceted protein that plays a critical role in maintaining genome stability and cellular homeostasis. Its dysregulation has been linked to various diseases, including cancer and Fanconi anemia. Further research is needed to fully elucidate the role of RPA3 in maintaining genome stability and to understand its implications in human disease.
