Mucin-5AC (MUC-5AC) is a protein that in humans is encoded by the MUC5AC gene.^[5][6][7]

MUC-5AC is a large gel-forming glycoprotein. In the respiratory tract it protects against infection by binding to inhaled pathogens that are subsequently removed by mucociliary clearance. Overproduction of MUC-5AC can contribute to diseases such as asthma and chronic obstructive pulmonary disease,^[8] and has also been associated with greater protection against influenza infection.^[9]

This gene has been linked to mucus hypersecretion in the respiratory tract and is associated to chronic obstructive pulmonary disease (COPD).^[10]
