Background	Keratin polypeptides 8 (basic keratin) and 18 (acidic keratin) exist in combination as K8/K18 which are the cytoskeletal intermediate filament proteins of hepatocytes while K8/K18/K19 are the keratins of hepatobiliary ductal cells. Hepatocyte K8/K18 are highly abundant and behave as stress proteins with injury-inducible expression. K8 and K18 are cytoprotective stress proteins that play a central role in guarding hepatocytes from apoptosis. Hepatocellular carcinoma have been reportedly defined by the use of antibodies that recognize only cytokeratins 8 and 18. K18 Ser33 as an interphase phosphorylation site, which increases its phosphorylation during mitosis in cultured cells and regenerating liver, and as an in vitro cdc2 kinase phosphorylation site.Phosphorylation of Ser33 and Ser52 are involved in keratin subcellular distribution.
Synonyms	CYK18; K18
Reference Data
Protein Pathways	Pathogenic Escherichia coli infection
