- * Surfactant associated polypeptide SP-C palmitoylation sites *
- ***************************************************************
-
- 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 [1].
-
- -Consensus pattern: I-P-C-C-P-V
- [The two C's are palmitoylated]
- -Sequences known to belong to this class detected by the pattern: ALL, except
- for dog SP-C, in which the second Cys is replaced by Phe [2].
- -Other sequence(s) detected in SWISS-PROT: NONE.
