Summaries for JAM2 Gene

Entrez Gene Summary for JAM2 Gene

  • 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]

GeneCards Summary for JAM2 Gene

JAM2 (Junctional Adhesion Molecule 2) is a Protein Coding gene. Among its related pathways are Cell surface interactions at the vascular wall and Blood-Brain Barrier and Immune Cell Transmigration: VCAM-1/CD106 Signaling Pathways. GO annotations related to this gene include protein heterodimerization activity. An important paralog of this gene is JAM3.
