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

MUC-5AC is a large gel-forming glycoprotein. In the respiratory tract, it protects against infection by binding to inhaled pathogens, which 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]
