SCGB1A1 encodes a small, secreted, disulfide-linked dimeric protein, the founding member of the secretoglobin family. It is specifically expressed in club cells of the airway epithelium and plays multiple roles in lung physiology and immune regulation. It possesses anti-inflammatory properties and protects against epithelial damage.
