KERATINS OR CYTOKERATINS – A REVIEW ARTICLE
Praveen Awasthi, Amit Thahriani, Amritaksha Bhattacharya

Epithelial tissues function to protect the organism from physical, chemical, and microbial damage and are essential for survival. To perform this role, epithelial keratinocytes undergo a well-defined differentiation program that results in the expression of structural proteins which maintain the integrity of epithelial tissues and function as a protective barrier. This review focuses on structural proteins of the epidermis and oral mucosa. Keratin proteins comprise the predominant cytoskeletal component of these epithelia. Keratin filaments are attached to the plasma membrane via desmosomes, and together these structural components form a three dimensional array within the cytoplasm of epithelial cells and tissues.
Key words: Cell, cytokeratins, cytoskeleton, keratin.
