Enables calcium ion binding activity. Predicted to be involved in cell-cell adhesion. Predicted to act upstream of or within BMP signaling pathway; hair follicle development; and keratinocyte differentiation. Predicted to be located in plasma membrane. Predicted to be integral component of membrane. Predicted to be active in desmosome. Used to study hypotrichosis. Human ortholog(s) of this gene implicated in hypotrichosis and hypotrichosis 6. Orthologous to human DSG4 (desmoglein 4). [provided by Alliance of Genome Resources, Apr 2022]
