Predicted to enable identical protein binding activity. Involved in several processes, including epithelial cell maturation; establishment of skin barrier; and positive regulation of epidermis development. Acts upstream of or within cornification; cuticle development; and hair follicle morphogenesis. Located in lysosomal membrane and trans-Golgi network membrane. Is expressed in alimentary system; genitourinary system; naris; skin; and thymus. Used to study atopic dermatitis. Orthologous to human TMEM79 (transmembrane protein 79).
