| Gene Symbol | KRT20 |
| Gene Full Name | keratin 20, type I |
| Background | Cytokeratin 20 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. This cytokeratin is a major cellular protein of mature enterocytes and goblet cells and is specifically expressed in the gastric and intestinal mucosa. The type I cytokeratin genes are clustered in a region of chromosome 17q12-q21. [provided by RefSeq, Jul 2008] |
| Function | Cytokeratin 20 plays a significant role in maintaining keratin filament organization in intestinal epithelia. When phosphorylated, plays a role in the secretion of mucin in the small intestine. [UniProt] |

| Research Area | CK7/CK20 Carcinoma Study antibody |
| Calculated MW | 48 kDa |
| PTM | Hyperphosphorylation at Ser-13 occurs during the early stages of apoptosis but becomes less prominent during the later stages. Phosphorylation at Ser-13 also increases in response to stress brought on by cell injury (By similarity). Proteolytically cleaved by caspases during apoptosis. Cleavage occurs at Asp-228. [UniProt] |

Flow Cytometry: HT-29 cells stained with ARG66248 anti-Cytokeratin 20 antibody [SQab1737] (Red). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% TritonX-100 for 15 min. The cells were then incubated in the primary antibody at 1:1000 dilution in 1x PBS/1% BSA for 30 min at 4°C. The secondary antibody used was a Goat anti-rabbit Alexa Fluor® 488 (IgG H+L) at 1:2000 dilution for 20 min at 4°C. Unlabelled sample (Blue) was used as a control.
