MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a transmembrane protein with two extracellular Kunitz domains that inhibits a variety of serine proteases. The protein inhibits HGF activator which prevents the formation of active hepatocyte growth factor. This gene is a putative tumor suppressor, and mutations in this gene result in congenital sodium diarrhea. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2009]
PHENOTYPE: Homozygous embryos carrying an insertional mutation fail to progress to the headfold stage and die at gastrulation displaying a severe clefting of the embryonic ectoderm at E7.5. [provided by MGI curators]
