MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a lung surfactant protein that is a member of a subfamily of C-type lectins called collectins. The encoded protein binds specific carbohydrate moieties found on lipids and on the surface of microorganisms. This protein plays an essential role in surfactant homeostasis and in the defense against respiratory pathogens. Mutations in this gene are associated with idiopathic pulmonary fibrosis. Alternate splicing results in multiple transcript variants. [provided by RefSeq, May 2010]
PHENOTYPE: Homozygotes for targeted null mutations exhibit impaired lung response to hyperventilation, reduced resistance to pulmonary infections, and enhanced pulmonary inflammatory response to lipopolysaccharide. [provided by MGI curators]
