Pulmonary surfactant-associated protein D (SFTPD)

Contributes to the lung's defense against inhaled microorganisms, organic antigens and toxins. Interacts with compounds like bacterial lipopolysaccharides, oligosaccharides and fatty acids and modulates leukocyte action in immune reaction.

May participate in the extracellular reorganization or turnover of pulmonary surfactant. Binds strongly maltose residues and to a lesser extent other alpha-glucosyl moieties.
