Summary

JAML (junction adhesion molecule like, HGNC:19084) is a protein-coding gene on chromosome 11q23.3, encoding Junctional adhesion molecule-like (Q86YT9). Transmembrane protein of the plasma membrane of leukocytes that control their migration and activation through interaction with CXADR, a plasma membrane receptor found on adjacent epithelial and endothelial cells.

Enables integrin binding activity and protein homodimerization activity. Involved in heterophilic cell-cell adhesion via plasma membrane cell adhesion molecules and myeloid leukocyte migration. Located in bicellular tight junction; nucleoplasm; and plasma membrane.

Function. Transmembrane protein of the plasma membrane of leukocytes that control their migration and activation through interaction with CXADR, a plasma membrane receptor found on adjacent epithelial and endothelial cells. The interaction between both receptors mediates the activation of gamma-delta T-cells, a subpopulation of T-cells residing in epithelia and involved in tissue homeostasis and repair. Upon epithelial CXADR-binding, JAML induces downstream cell signaling events in gamma-delta T-cells through PI3-kinase and MAP kinases. It results in proliferation and production of cytokines and growth factors by T-cells that in turn stimulate epithelial tissues repair. It also controls the transmigration of leukocytes within epithelial and endothelial tissues through adhesive interactions with epithelial and endothelial CXADR.

Subunit / interactions. Homodimer; active form in leukocyte-endothelial cell adhesion. Interacts (homodimeric form) with CXADR. Interacts (via cytoplasmic domain) with the PI3 kinase; upon CXADR-binding. Interacts with ITGA4 and ITGB1; integrin alpha-4/beta-1 may regulate leukocyte to endothelial cells adhesion by controlling JAML homodimerization.

Subcellular location. Cell membrane. Cell junction.

Tissue specificity. Expression is restricted to the hematopoietic tissues with the exception of liver. Expressed in fetal liver, spleen and thymus. Preferentially expressed by mature leukocytes (at protein level).

Domain organisation. The Ig-like V-type domain 1 mediates interaction with CXADR. The Ig-like V-type domain 2 may also play a role in the interaction.

Induction. Up-regulated upon retinoic acid, Me2SO and PMA treatment in differentiating myeloid leukemia cells.

Similarity. Belongs to the immunoglobulin superfamily.
