UniProt data
UniProt name: JAML_HUMAN (Q86YT9)
Gene name: JAML {ECO:0000312|HGNC:HGNC:19084}; Synonyms=AMICA1
Organism: Homo sapiens (Human).
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. {ECO:0000269|PubMed:12869515, ECO:0000269|PubMed:15800062, ECO:0000269|PubMed:18948633, ECO:0000269|PubMed:19064666}.
