Enables actin filament binding activity and protein homodimerization activity. Involved in centrosome localization and regulation of cilium assembly. Acts upstream of or within nuclear migration. Located in nuclear envelope. Is expressed in several structures, including alimentary system; ear; genitourinary system; musculoskeletal system; and nervous system. 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). [provided by Alliance of Genome Resources, Apr 2022]
