Other Information

**Key Characteristics** KRT7 is a type II keratin, which is distinct from type I keratins in terms of its expression pattern and function. Unlike type I keratins, which are primarily expressed in the epidermis, KRT7 is widely expressed in various epithelial tissues, including the lungs, skin, and gastrointestinal tract. KRT7 is also unique in its ability to form dimers with other keratin proteins, such as KRT6A, to create a stable intermediate filament network. This dimerization is essential for maintaining the structural integrity of epithelial cells and protecting them against mechanical stress. **Pathways and Functions** KRT7 is involved in several cellular pathways that regulate epithelial function and integrity. These include: 1. **Formation of the Cornified Envelope**: KRT7 is essential for the formation of the cornified envelope, a complex structure that provides mechanical strength to the epidermis. 2. **Cell Differentiation**: KRT7 plays a crucial role in regulating cell differentiation in epithelial tissues, including the development of skin and lung epithelium. 3. **Cell Adhesion**: KRT7 is involved in cell adhesion, particularly in the formation of tight junctions between epithelial cells. 4. **Mechanical Stress Response**: KRT7 helps to protect epithelial cells against mechanical stress by maintaining the structural integrity of the intermediate filament network. **Clinical Significance** Dysregulation of KRT7 has been implicated in various diseases, including: 1. **Cancer**: Alterations in KRT7 expression have been observed in several types of cancer, including breast, lung, and skin cancers. 2. **Autoimmune Disorders**: Abnormal KRT7 expression has been linked to autoimmune disorders, such as pemphigus and psoriasis. 3. **Skin Conditions**: Mutations in the KRT7 gene have been associated with skin conditions, such as epidermolysis bullosa simplex. 4. **Respiratory Diseases**: KRT7 has been implicated in the pathogenesis of respiratory diseases, such as chronic obstructive pulmonary disease (COPD). In conclusion, KRT7 is a critical component of the intermediate filament cytoskeleton, playing a vital role in maintaining epithelial integrity and function. Its dysregulation has been implicated in various diseases, highlighting the importance of KRT7 in disease pathogenesis. Further research is needed to fully elucidate the mechanisms by which KRT7 regulates epithelial function and to explore its therapeutic potential in disease treatment.

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.
