Protein Name: Calcium-activated chloride channel regulator 1

UniprotKB/SwissProt ID: A8K7I4 (A8K7I4)

Gene Name: CLCA1

Organism: Homo sapiens (Human)

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

Other Modifications: View all modification sites in dbPTM

Protein Subcellular Localization: Secreted, extracellular space. Cell membrane
