FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene belongs to the immunoglobulin superfamily, and the junctional adhesion molecule (JAM) family. The protein encoded by this gene is a type I membrane protein that is localized at the tight junctions of both epithelial and endothelial cells. It acts as an adhesive ligand for interacting with a variety of immune cell types, and may play a role in lymphocyte homing to secondary lymphoid organs. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jul 2012]
PHENOTYPE: Mice homozygous for a knock-out allele are viable, fertile and overtly normal with no detectable spermatogenesis abnormalities or defects in embryonic, neural and hematopoietic stem cell properties. [provided by MGI curators]
