    Summary
    Predicted to enable cell adhesion molecule binding activity. Involved in adult chitin-based cuticle pattern formation; compound eye morphogenesis; and regulation of establishment of planar polarity. Predicted to be active in cell-cell junction. Predicted to be integral component of plasma membrane. Is expressed in several structures, including adult head; imaginal disc; and presumptive embryonic/larval system.
