| Specificity | The antibody is specific to human cytokeratin 19 and is reactive with cells of epithelial origin. Cytokeratin 19 is the smallest human cytokeratin (40 kDa) and is found in many simple and invariably in some non-keratinising stratified squamous epithelia. All adenocarcinomas tested have been positive for cytokeratin 19. FUSION PARTNER: Px63 Ag 8.653 myeloma cell line |

| Entrez Gene Summary | The protein encoded by this gene is a member of the keratin family. The keratins are intermediate filament proteins responsible for the structural integrity of epithelial cells and are subdivided into cytokeratins and hair keratins. The type I cytokeratins consist of acidic proteins which are arranged in pairs of heterotypic keratin chains. Unlike its related family members, this smallest known acidic cytokeratin is not paired with a basic cytokeratin in epithelial cells. It is specifically expressed in the periderm, the transiently superficial layer that envelopes the developing epidermis. The type I cytokeratins are clustered in a region of chromosome 17q12-q21. |

| UniProt Summary | FUNCTION: SwissProt: P08727 # Involved in the organization of myofibers. Together with KRT8, helps to link the contractile apparatus to dystrophin at the costameres of striated muscle. SIZE: 400 amino acids; 44092 Da SUBUNIT: Heterotetramer of two type I and two type II keratins. Interacts with PNN and the actin-binding domain of DMD. Interacts with HCV core protein. TISSUE SPECIFICITY: Expressed in a defined zone of basal keratinocytes in the deep outer root sheath of hair follicles. Also observed in sweat gland and mammary gland ductal and secretory cells, bile ducts, gastrointestinal tract, bladder urothelium, oral epithelia, esophagus, ectocervical epithelium (at protein level). Expressed in epidermal basal cells, in nipple epidermis and a defined region of the hair follicle. Also seen in a subset of vascular wall cells in both the veins and artery of human umbilical cord, and in umbilical cord vascular smooth muscle. Observed in muscle fibers accumulating in the costameres of myoplasm at the sarcolemma in structures that contain dystrophin and spectrin.DEVELOPMENTAL STAGE: Present in hair follicles at all stages of development. DOMAIN: SwissProt: P08727 This keratin differs from all other IF proteins in lacking the C-terminal tail domain. SIMILARITY: Belongs to the intermediate filament family. MISCELLANEOUS: There are two types of cytoskeletal and microfibrillar keratin: I (acidic; 40-55 kDa) and II (neutral to basic; 56-70 kDa). |
