SP-B is present on the surface of exocytosed surfactant particles. Antibodies against SP-B stabilize the released particles when contacting the air-liquid interface, precluding their transformation and the formation of surface films. SP-B acts as an essential, preformed molecular key in the initial stages of surfactant unpacking and surface film formation.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
