As well as endocrine and exocrine tissues and mesothelial cells. It is unreactive with stratified squamous epithelia (esophagus, epidermis, ectocervix). In transitional epithelium of the bladder RGE53 only reacts with the superficial (umbrella) cells. RGE53 can distinguish adenocarcinomas and mesotheliomas from squamous cell carcinoma and non-epithelial tumours. The antibody is directed against 45 kD cytokeratin protein (cytokeratin 18). Cross reactivity with; Keratin from most mammals, birds. View All» Molecular Weight: 45 kD View All» Immunogen: Cytoskeletal preparation from HeLa cells View All» Clone: RGE53 View All» Isotype: IgG1 View All» Background Information: Cytokeratins are a subfamily of intermediate filament proteins and are characterized by a remarkable biochemical diversity, represented in epithelial tissues by at least 20 different polypeptides. They range in molecular weight from between 40 kDa and 68 kDa and isoelectric pH between 4.9 - 7.8, The individual cytokeratin polypeptides are designated 1-20. The various epithelia in the human body usually express cytokeratins which are not only characteristic of the type of epithelium, but also related to the degree of maturation or differentiation within an epithelium. Cytokeratin subtype expression patterns are used to an increasing extent in the distinction of different types of epithelial malignancies. View All» Species Reactivity:

Immunocytochemistry: (10μg/mL) Light fixation with 4% formalin, 2.5% PFA ( 5-10 minutes room temperature) or acetone. {See, Barrett, et al 2001} Permeabilization with 0.2% triton X-100 in blocking buffer if using formalin or PFA fixations. Flow cytometry: Acetone fixed/ethanol fixed cells {See Mezosi, E et al, 2002}. Optimal working dilutions must be determined by the end user.

        View All» Entrez Gene Summary: KRT18 encodes the type I intermediate filament chain keratin 18. Keratin 18, together with its filament partner keratin 8, are perhaps the most commonly found members of the intermediate filament gene family. They are expressed in single layer epithelial tissues of the body. Mutations in this gene have been linked to cryptogenic cirrhosis. Two transcript variants encoding the same protein have been found for this gene. View All» UniProt Summary: FUNCTION: SwissProt: P05783 # Involved in the uptake of thrombin-antithrombin complexes by hepatic cells (By similarity). When phosphorylated, plays a role in filament reorganization. Involved in the delivery of mutated CFTR to the plasma membrane. Together with KRT8, is involved in interleukin-6 (IL-6)-mediated barrier protection.SIZE: 430 amino acids; 48058 Da SUBUNIT: Heterotetramer of two type I and two type II keratins. Keratin-18 associates with keratin-8. Interacts with the thrombin- antithrombin complex (By similarity). Interacts with PNN, HCV core protein and mutated CFTR. Interacts with YWHAE, YWHAH and YWHAZ only when phosphorylated. Interacts with DNAJB6, TCHP and TRADD.SUBCELLULAR LOCATION: Cytoplasm, perinuclear region.TISSUE SPECIFICITY: Expressed in colon, placenta, liver and very weakly in exocervix. Increased expression observed in lymph nodes of breast carcinoma.PTM: Phosphorylation at Ser-34 increases during mitosis. Hyperphosphorylated at Ser-53 in diseased cirrhosis liver. Phosphorylation increases by IL-6. & Proteolytically cleaved by caspases during epithelial cell apoptosis. Cleavage occurs at Asp-238 by either caspase-3, caspase-6 or caspase-7.DISEASE:SwissProt: P05783 # Defects in KRT18 are a cause of cryptogenic cirrhosis [MIM:215600].SIMILARITY: SwissProt: P05783 ## 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).
