    Summary
    Enables actin binding activity and protein kinase binding activity. Involved in several processes, including cytoskeleton organization; endoplasmic reticulum localization; and larval visceral muscle development. Located in Z disc; nuclear outer membrane; and perinuclear region of cytoplasm. Colocalizes with actin filament. Is expressed in several structures, including adult head; adult heart; epithelium; germline cell; and muscle cell. Used to study Emery-Dreifuss muscular dystrophy. Human ortholog(s) of this gene implicated in arthrogryposis multiplex congenita (multiple); bipolar disorder; cerebellar ataxia (multiple); and muscular dystrophy (multiple). Orthologous to human SYNE1 (spectrin repeat containing nuclear envelope protein 1) and SYNE2 (spectrin repeat containing nuclear envelope protein 2).
