Loss of E-cadherin and up-regulation of mesenchymal cadherins, a hallmark of the
epithelial-mesenchymal transition, contributes to migration and dissemination of
cancer cells. Expression of human cadherin-11 (Cad11), also known as osteoblast
cadherin, in prostate cancer increases the migration of prostate cancer cells.
How Cad11 mediates cell migration is unknown. Using the human Cad11 cytoplasmic
domain in pulldown assays, we identified human angiomotin (Amot), known to be
involved in cell polarity, migration, and Hippo pathway, as a component of the
Cad11 protein complex. Deletion analysis showed that the last C-terminal 10 amino
acids in Cad11 cytoplasmic domain are required for Amot binding. Further, Cad11
preferentially interacts with Amot-p80 than Amot-p130 isoform and binds directly
to the middle domain of Amot-p80. Cad11-Amot interaction affects Cad11-mediated
cell migration, but not homophilic adhesion, as deletion of Amot binding motif of
Cad11 (Cad11-?Amot) did not abolish Cad11-mediated cell-cell adhesion of mouse L
cells, but significantly reduced Cad11-mediated cell migration of human C4-2B4
and PC3-mm2 prostate cancer cells and human HEK293T cells. Together, our studies
identified Amot-p80 as a novel component of the Cad11 complex and demonstrated
that Amot-p80 is critical for Cad11-mediated cell migration.
