 1-144 1.49e-82

Pulmonary surfactant proteins; 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

BRICHOS domain; The BRICHOS domain is about 100 amino acids long. It is found in a variety of proteins implicated in dementia, respiratory distress and cancer. Its exact function is unknown; roles that have been proposed for it include (a) in targeting of the protein to the secretory pathway, (b) intramolecular chaperone-like function, and (c) assisting the specialized intracellular protease processing system. This C-terminal domain is embedded in the endoplasmic reticulum lumen, and binds to the N-terminal, transmembrane, SP_C, pfam08999, provided that it is in non-helical conformation. Thus the Brichos domain of proSP-C is a chaperone that induces alpha-helix formation of an aggregation-prone TM region.

 15-40 6.34e-07

Surfactant protein C, N terminal propeptide; The N-terminal propeptide of surfactant protein C adopts an alpha-helical structure, with turn and extended regions. It's main function is the stabilization of metastable surfactant protein C (SP-C), since the latter can irreversibly transform from its native alpha-helical structure to beta-sheet aggregates and form amyloid-like fibrils. The correct intracellular trafficking of proSP-C has also been reported to depend on the propeptide.
