General annotation (Comments)

Function	Gel-forming glycoprotein of gastric and respiratoy tract epithelia that protects the mucosa from infection and chemical damage by binding to inhaled microrganisms and particles that are subsequently removed by the mucocilary system.
Subunit structure	Multimeric. Interacts with H.pylori in the gastric epithelium, Barrett's esophagus as well as in gastric metaplasia of the duodenum (GMD). Ref.12
Subcellular location	Secreted Ref.13.
Tissue specificity	Highly expressed in surface mucosal cells of respiratory tract and stomach epithelia. Overexpressed in a number of carcinomas. Also expressed in Barrett's esophagus epithelium and in the proximal duodenum. Ref.6 Ref.12
Domain	The cysteine residues in the Cys-rich subdomain repeats are not involved in disulfide bonding.
Post-translational modification	C-, O- and N-glycosylated. O-glycosylated on the Thr-/Ser-rich tandem repeats. C-mannosylation in the Cys-rich subdomains may be required for proper folding of these regions and for export from the endoplasmic reticulum during biosynthesis. Ref.11 Ref.13 Proteolytic cleavage in the C-terminal is initiated early in the secretory pathway and does not involve a serine protease. The extent of cleavage is increased in the acidic parts of the secretory pathway. Cleavage generates a reactive group which could link the protein to a primary amide.
Sequence similarities	Contains 1 CTCK (C-terminal cystine knot-like) domain. Contains 2 VWFC domains. Contains 4 VWFD domains.
Sequence caution	The sequence AAA18431.1 differs from that shown. Reason: Frameshift at several positions. The sequence AAC15950.1 differs from that shown. Reason: Frameshift at positions 24, 44, 671 and 683. The sequence CAA88307.1 differs from that shown. Reason: Frameshift at position 5024. The sequence CAH56330.1 differs from that shown. Reason: Frameshift at position 4616.
