Predicted to enable calcium ion binding activity. Predicted to be involved in homophilic cell adhesion via plasma membrane adhesion molecules. Predicted to be located in membrane. Is an ortholog of C. elegans Y52B11A.11 and
hmr-1. In C. elegans,
hmr-1 is involved in several processes, including cell-cell adhesion mediated by cadherin; cytoskeleton organization; and gastrulation.
