Other Information

**Key Characteristics:** 1. **Ankyrin Repeat Domain**: KRIT1 contains an ankyrin repeat domain, which is crucial for its interactions with other proteins and regulation of cellular processes. 2. **Negative Regulation of Angiogenesis**: KRIT1 acts as a negative regulator of angiogenesis, a process essential for tumor growth and metastasis. Its suppression of angiogenesis prevents excessive tissue growth and maintains tissue homeostasis. 3. **Cell-Cell Junctions**: KRIT1 is involved in regulating cell-cell junctions, which are essential for maintaining tissue integrity and preventing excessive cell migration. 4. **Cytoskeleton Dynamics**: KRIT1 regulates cytoskeleton dynamics, which is critical for cell migration, proliferation, and differentiation. **Pathways and Functions:** 1. **Angiogenesis**: KRIT1 negatively regulates angiogenesis by inhibiting the activation of pro-angiogenic signaling pathways. 2. **Cell-Cell Junctions**: KRIT1 regulates cell-cell junctions by interacting with proteins involved in adhesion and signaling. 3. **Cytoskeleton Dynamics**: KRIT1 regulates cytoskeleton dynamics by interacting with microtubules and other cytoskeletal components. 4. **Protein Binding**: KRIT1 interacts with various proteins, including GTPases, phosphatidylinositol-4,5-bisphosphate, and integrins, to regulate cellular processes. **Clinical Significance:** KRIT1's role in regulating angiogenesis and cell-cell junctions makes it an attractive target for the treatment of various diseases, including cancer, cardiovascular disease, and neurological disorders. Aberrant expression of KRIT1 has been observed in several cancers, including glioblastoma and breast cancer, suggesting its potential as a diagnostic biomarker and therapeutic target. Additionally, KRIT1's involvement in neuronal function and development highlights its potential as a therapeutic target for neurological disorders, such as Alzheimer's disease and Parkinson's disease. **Implications:** Further research is necessary to fully elucidate the mechanisms by which KRIT1 regulates cellular processes and its role in various diseases. However, its identification as a negatively regulated protein with potential therapeutic applications underscores the importance of KRIT1 in maintaining tissue homeostasis and preventing disease.

Database document:

This is a preview of the gene's schema. Only a few entries are kept for 'singleCellExpressions,' 'mRNAExpressions,' and other large data arrays for visualization purposes. You can zoom in with the mouse wheel for a closer view, and the text will adjust automatically if necessary. For the full schema, download it here.
