FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a carcinoma-associated antigen and is a member of a family that includes at least two type I membrane proteins. This antigen is expressed on most normal epithelial cells and gastrointestinal carcinomas and functions as a homotypic calcium-independent cell adhesion molecule. The antigen is being used as a target for immunotherapy treatment of human carcinomas. Mutations in this gene result in congenital tufting enteropathy. [provided by RefSeq, Dec 2008]
PHENOTYPE: Homozygous null mice display embryonic lethality during organogenesis with decreased embryo size, impaired labyrinth layer development and decreased number of trophoblast giant cells. Mice homozygous for another knock-out allele exhibit impaired intestinal tight junctions with lethality. [provided by MGI curators]
