|WB||WB: 1/500 - 1/1000. Detects a band of approximately 48 kDa (predicted molecular weight: 48 kDa).|
|ICC/IF||ICC/IF: 1/500 - 1/1000.|
- FunctionInvolved 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.
- Tissue specificityExpressed in colon, placenta, liver and very weakly in exocervix. Increased expression observed in lymph nodes of breast carcinoma.
- Involvement in diseaseDefects in KRT18 are a cause of cirrhosis (CIRRH) [MIM:215600].
- Sequence similaritiesBelongs to the intermediate filament family.
modificationsPhosphorylation 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-glycosylated at multiple sites; glycans consist of single N-acetylglucosamine residues.
