Enzyme Function FUNCTION: May be involved in mediating calcium-activated chloride conductance. May play critical roles in goblet cell metaplasia, mucus hypersecretion, cystic fibrosis and AHR. May be involved in the regulation of mucus production and/or secretion by goblet cells. Involved in the regulation of tissue inflammation in the innate immune response. May play a role as a tumor suppressor. Induces MUC5AC (By similarity). {ECO:0000250}.

Interact With
Induction INDUCTION: Strongly up-regulated in bronchioles with recurrent airway obstruction (RAO). {ECO:0000269|PubMed:15879574}.
Subcellular Location SUBCELLULAR LOCATION: Secreted, extracellular space {ECO:0000250}.
Modified Residue
Post Translational Modification PTM: Glycosylated. {ECO:0000269|PubMed:15879574}.; PTM: The translation product is autoproteolytically cleaved by the metalloprotease domain in the endoplasmic reticulum into a N-terminal and a C-terminal products that remain physically associated with each other. The cleavage is necessary for calcium-activated chloride channel (CaCC) activation activity. {ECO:0000250|UniProtKB:A8K7I4}.
