Research Abstract

A cell adhesion molecule, CADM1, is involved in the formation and maintenance of epithelial cell adhesion by interacting with actin-binding proteins. By analyzing the dynamic regulation of CADM1 complex using fluorescence-tagged molecules, CADM1 complex was found to be exchanged continuously in confluent cells. In contrast, in adult T-cell leukemia(ATL), CADM1 played a role in trans-endothelial migration through the formation of the protrusion at the attachment sites of ATL and endothelial cells.
