Gene ID58494
SpeciesHomo sapiens (Human)
Gene Namejunctional adhesion molecule 2
Gene Symbol JAM2
SynonymsJAMB; CD322; JAM-B; VEJAM; PRO245; VE-JAM; C21orf43;
Alternate namesjunctional adhesion molecule B; JAM-2; JAM-IT/VE-JAM; vascular endothelial junction-associated molecule;
Chromosome21
Map Location21q21.2
SummaryThis 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]
