Specificity: Phospho-Cytokeratin 18 (S33) Polyclonal Antibody detects endogenous levels of Cytokeratin 18 protein only when phosphorylated at S33.
Immunogen: The antiserum was produced against synthesized peptide derived from the human Keratin 18 around the phosphorylation site of Ser33 at the amino acid range 1-50
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.
