Acts upstream of or within Notch signaling pathway and hair cycle process. Located in cell surface; ciliary membrane; and stereocilium. Is expressed in several structures, including genitourinary system; gut; nervous system; sensory organ; and tooth. Human ortholog(s) of this gene implicated in autosomal recessive nonsyndromic deafness 98 and ectodermal dysplasia 14. Orthologous to human TSPEAR (thrombospondin type laminin G domain and EAR repeats). [provided by Alliance of Genome Resources, Apr 2022]
