Short Description: |
This human KRT18 kit is a highly sensitive in-vitro chemiluminescent immunoassay for the measurement of trace amounts of analytes. |
Storage Instruction: |
If unopened the kit may be stored at 2-8°C for up to 1 month. If the kit will not be used within 1 month, store the components separately, according to the component table in the manual. |
Assay Time: |
3.5h |
Detection: |
Chemiluminescence |
Gene Symbol: |
KRT18 |
Gene ID: |
3875 |
Uniprot ID: |
K1C18_HUMAN |
Specificity: |
This kit recognizes Human CK-18/KRT18 in samples. No significant cross-reactivity or interference between Human CK-18/KRT18 and analogues was observed. |
Sample Type: |
Serum, plasma and other biological fluids |
Tissue Specificity | Expressed in colon, placenta, liver and very weakly in exocervix. Increased expression observed in lymph nodes of breast carcinoma. |
Post Translational Modifications | 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. O-GlcNAcylation increases solubility, and decreases stability by inducing proteasomal degradation. |
Function | Involved in the uptake of thrombin-antithrombin complexes by hepatic cells. 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. |
