Fat1 - FAT atypical cadherin 1

Involved in epithelial cell morphogenesis; establishment of epithelial cell apical/basal polarity involved in camera-type eye morphogenesis; and lens development in camera-type eye. Acts upstream of or within actin filament organization; cell-cell adhesion; and establishment or maintenance of cell polarity. Located in several cellular components, including apical plasma membrane; filopodium; and lamellipodium. Is active in plasma membrane. Is expressed in several structures, including alimentary system; central nervous system; embryo ectoderm; embryo mesenchyme; and sensory organ. Used to study facioscapulohumeral muscular dystrophy and nephrotic syndrome. Orthologous to human FAT1 (FAT atypical cadherin 1). [provided by Alliance of Genome Resources, Apr 2022]
