Junctional adhesion molecule A (F11r)

Appears to play a role in epithelial tight junction formation. Appears early in primordial forms of cell junctions and recruits PARD3 (PubMed:11447115).

The institution of the PARD6- PARD3 complicated may prevent the interaction of PARD3 with JAM1, thereby preventing tight junction assembly (PubMed:11447115). Plays a role in regulating monocyte transmigration involved with ethics of epithelial barrier (PubMed:9660867).
