Gene Information

human ... KRT20(54474)

General description

Anti-Keratin 20 Antibody detects endogenous levels of total Keratin 20 protein.
The gene KRT20 (keratin 20) is mapped to human chromosome 17. The gene encodes an intermediate filament which is mainly expressed in the gastrointestinal epithelial cells and epidermal Merkel cells. The protein is a type 1 keratin.

Immunogen

The antiserum was produced against synthesized peptide derived from human Keratin 20.

Immunogen Range: 375-424

Biochem/physiol Actions

KRT20 (keratin 20) helps in intermediate filament organization. In metastatic colorectal cancer, it can be used as a biomarker for checking circulating tumor cells.

Approximately 15% of colorectal cancer (CRC) cases exhibit microsatellite instability (MSI), which appears to be associated with unique biological behavior. The present study presents a case of appendiceal carcinoma associated with MSI that responded well to adjuvant chemotherapy. Clinical, pathological

Cytokeratin 20 (CK20) is a well-established marker for colon epithelium. Herein, we suggest that CK20 is a biomarker for detecting circulating tumor cells (CTCs) in patients with metastatic colorectal cancer. Blood specimens (7.5 mL) were collected during surgery after liver mobilization

Of the >20 epithelial keratins, keratin 20 (K20) has an unusual distribution and is poorly studied. We began to address K20 function, by expressing human wild-type and Arg80-->His (R80H) genomic (18 kb) and cDNA K20 in cells and mice. Arg80
