Predicted to enable cadherin binding activity and calcium ion binding activity. Predicted to be involved in several processes, including calcium-dependent cell-cell adhesion via plasma membrane cell adhesion molecules; cell-cell junction organization; and heart development. Predicted to act upstream of or within several processes, including animal organ development; condensed mesenchymal cell proliferation; and post-anal tail morphogenesis. Predicted to be located in apical part of cell. Predicted to be part of catenin complex. Predicted to be active in adherens junction. Human ortholog(s) of this gene implicated in Van Maldergem syndrome 1 and mitral valve prolapse. Orthologous to human DCHS1 (dachsous cadherin-related 1).
