Predicted to enable transmembrane signaling receptor activity. Acts upstream of or within several processes, including animal organ development; positive regulation of NIK/NF-kappaB signaling; and positive regulation of gene expression. Located in apical part of cell and plasma membrane. Is expressed in several structures, including embryo ectoderm; integumental system; male accessory gland; oral region epithelium; and tooth. Used to study hypohidrotic ectodermal dysplasia. Human ortholog(s) of this gene implicated in ectodermal dysplasia 10A and ectodermal dysplasia 10B. Orthologous to human EDAR (ectodysplasin A receptor). [provided by Alliance of Genome Resources, Apr 2022]
