SF_P

Pulmonary surfactant proteins
SF_P
SMART accession number:SM00019
Description: Pulmonary surfactant associated proteins promote alveolar stability by lowering the surface tension at the air-liquid interface in the peripheral air spaces. SP-C, a component of surfactant, is a highly hydrophobic peptide of 35 amino acid residues which is processed from a larger precursor protein. SP-C is post-translationally modified by the covalent attachment of two palmitoyl groups on two adjacent cysteines
