TissueNA
Tissue SpecificityDetected on round and elongated spermatids (at protein level) (PubMed:15372036). Highest expression in placenta, brain and kidney. Significant expression is detected on platelets. Expressed in intestinal mucosa cells. Expressed in the vascular endothelium. Found in serum (at protein level). Also detected in the synovial fluid of patients with rheumatoid arthritis, psoriatic arthritis or ostearthritis (at protein level). {ECO:0000269|PubMed:11590146, ECO:0000269|PubMed:11944976, ECO:0000269|PubMed:12208882, ECO:0000269|PubMed:15194813, ECO:0000269|PubMed:15372036, ECO:0000269|PubMed:15994945, ECO:0000269|PubMed:20592283}.

Cell junction, tight junction {ECO:0000269|PubMed:28196865}. Note=Detected in the acrosome region in developing spermatids (By similarity). In epithelial cells, it is expressed at desmosomes but not at tight junctions (PubMed:15194813). Localizes at the cell surface of endothelial cells;
treatment of endothelial cells with vascular endothelial growth factor stimulates recruitment of JAM3 to cell-cell contacts (PubMed:15994945). {ECO:0000250|UniProtKB:Q9D8B7}.;
[Soluble form of JAM-C]: Secreted {ECO:0000269|PubMed:20592283}.
