JAML or Junctional Adhesion Molecule-Like, or AMICA1 is a JAM transmembrane protein family member. It is composed of two extracellular immunoglobulin-like domains, a membrane-spanning region, and a cytoplasmic tail involved in activation signaling. A known ligand of JAML is Coxsackie virus and Adenovirus Receptor (
