Surfactant protein C (SP-C), is one of the pulmonary surfactant proteins. In humans this is encoded by the SFTPC gene.[1][2][3]
It is a membrane protein which manufactures surfactant.
The propeptide of pulmonary surfactant C has an N-terminal alpha-helical segment whose suggested function was stabilization of the protein structure, since the latter can irreversibly transform from its native alpha-helical structure to beta-sheet aggregates and form amyloid fibrils. The correct intracellular trafficking of proSP-C has also been reported to depend on the propeptide.[4]
Clinical significance
It is associated with surfactant metabolism dysfunction type 2.
Humans and animals born lacking SP-C tend to develop progressive interstitial lung disease.
