SFTPB, or pulmonary-associated surfactant protein B, is an amphipathic surfactant protein essential for lung function and homeostasis after birth. Pulmonary surfactant-associated proteins promote alveolar stability by lowering the surface tension at the air-liquid interface in the peripheral air spaces. These proteins are composed of 90% lipids and 10% proteins, and include plasma proteins and apolipoproteins SPA, SPB, SPC and SPD. There are several alternatively spliced transcript variants for this gene, all encoding the same protein.
