Involved in compound eye development. Located in adherens junction and apical plasma membrane. Is expressed in several structures, including Malpighian tubule; embryonic/larval salivary gland; eye disc morphogenetic furrow; gut section; and imaginal disc. Orthologous to human LNX1 (ligand of numb-protein X 1); LNX2 (ligand of numb-protein X 2); and STXBP4 (syntaxin binding protein 4).
