General annotation (Comments)

Function	May function in transmigration of leukocytes through epithelial and endothelial tissues. Expressed at the plasma membrane of polymorphonuclear leukocytes, it mediates adhesive interactions with CXADR, a protein of the junctional complex of epithelial cells. Enhances myeloid leukemia cell adhesion to endothelial cells. Ref.1 Ref.7
Subunit structure	Interacts with CXADR. Ref.7
Subcellular location	Cell junction. Cell membrane; Single-pass type I membrane protein. Note: Localized at the plasma membrane in areas of cell-cell contacts and at the cell surface of PMN. Ref.1 Ref.7
Tissue specificity	Expression is restricted to the hematopoietic tissues with the exception of liver. Expressed in fetal liver, spleen and thymus. Ref.1
Induction	Up-regulated upon retinoic acid, Me2SO and PMA treatment in differentiating myeloid leukemia cells. Ref.1
Domain	The Ig-like V-type domain 2 mediates interaction with CXADR. Ref.1 Ref.7
Sequence similarities	Belongs to the immunoglobulin superfamily. Contains 2 Ig-like V-type (immunoglobulin-like) domains.
