Sun1 - Sad1 and UNC84 domain containing 1

Enables lamin binding activity. Involved in centrosome localization; meiotic attachment of telomere to nuclear envelope; and nucleokinesis involved in cell motility in cerebral cortex radial glia guided migration. Acts upstream of or within homologous chromosome pairing at meiosis. Located in acrosomal membrane and nuclear envelope. Is integral component of nuclear inner membrane. Is expressed in intercostal muscle; spermatocyte; and spermatozoon. Orthologous to human SUN1 (Sad1 and UNC84 domain containing 1). [provided by Alliance of Genome Resources, Apr 2022]
