3par

Surfactant Protein-A neck and carbohydrate recognition domain (NCRD) in the absence of ligandSurfactant Protein-A neck and carbohydrate recognition domain (NCRD) in the absence of ligand

FunctionFunction

[SFTPA_RAT] In presence of calcium ions, it binds to surfactant phospholipids and contributes to lower the surface tension at the air-liquid interface in the alveoli of the mammalian lung and is essential for normal respiration.
