== Function ==
[[http://www.uniprot.org/uniprot/PSPB_HUMAN PSPB_HUMAN]] Pulmonary surfactant-associated proteins promote alveolar stability by lowering the surface tension at the air-liquid interface in the peripheral air spaces. SP-B increases the collapse pressure of palmitic acid to nearly 70 millinewtons per meter.
