Pulmonary Surfactant-Associated Protein C definition

Pulmonary Surfactant-Associated Protein C
Pulmonary Surfactant Protein C; SP-C protein; Surfactant Polypeptide SP-C; Pulmonary Surfactant Associated Protein C; Pulmonary Surfactant Associated Protein SP C; SP C protein; SP-C, Surfactant Polypeptide; Surfactant Polypeptide SP C
A pulmonary surfactant associated protein that plays a role in alveolar stability by lowering the surface tension at the air-liquid interface. It is a membrane-bound protein that constitutes 1-2% of the pulmonary surfactant mass. Pulmonary surfactant-associated protein C is one of the most hydrophobic peptides yet isolated and contains an alpha-helical domain with a central poly-valine segment that binds to phospholipid bilayers.
