Summaries for JAM3 Gene

Entrez Gene Summary for JAM3 Gene

  • Tight junctions represent one mode of cell-to-cell adhesion in epithelial or endothelial cell sheets, forming continuous seals around cells and serving as a physical barrier to prevent solutes and water from passing freely through the paracellular space. The protein encoded by this immunoglobulin superfamily gene member is localized in the tight junctions between high endothelial cells. Unlike other proteins in this family, the this protein is unable to adhere to leukocyte cell lines and only forms weak homotypic interactions. The encoded protein is a member of the junctional adhesion molecule protein family and acts as a receptor for another member of this family. A mutation in an intron of this gene is associated with hemorrhagic destruction of the brain, subependymal calcification, and congenital cataracts. Alternative splicing results in multiple transcript variants.[provided by RefSeq, Apr 2011]

GeneCards Summary for JAM3 Gene

JAM3 (Junctional Adhesion Molecule 3) is a Protein Coding gene. Diseases associated with JAM3 include hemorrhagic destruction of the brain, subependymal calcification, and cataracts and porencephaly-microcephaly-bilateral congenital cataract syndrome. Among its related pathways are Integrin Pathway and Hemostasis. GO annotations related to this gene include protein homodimerization activity and integrin binding. An important paralog of this gene is JAM2.

UniProtKB/Swiss-Prot for JAM3 Gene

  • Participates in cell-cell adhesion. It is a counter-receptor for ITGAM, mediating leukocyte-platelet interactions and is involved in the regulation of transepithelial migration of polymorphonuclear neutrophils (PMN). The soluble form is a mediator of angiogenesis.

Disorders for JAM3 Gene

(1) OMIM Diseases for JAM3 Gene (606871)


  • Hemorrhagic destruction of the brain with subependymal calcification and cataracts (HDBSCC) [MIM:613730]: A syndrome characterized by congenital cataracts and severe brain abnormalities apparently resulting from hemorrhagic destruction of the brain parenchyma, including the cerebral white matter and basal ganglia. Patients manifest profound developmental delay, and other neurologic features included seizures, spasticity, and hyperreflexia. The clinical course is very severe resulting in death in infancy. Brain imaging shows multifocal intraparenchymal hemorrhage with associated liquefaction and massive cystic degeneration, and calcification in the subependymal region and in brain tissue. {ECO:0000269 PubMed:21109224, ECO:0000269 PubMed:23255084}. Note=The disease is caused by mutations affecting the gene represented in this entry.
