Enables importin-alpha family protein binding activity. Involved in asymmetric cell division and meiotic spindle assembly. Acts upstream of or within Golgi localization and positive regulation of axonogenesis. Located in Golgi apparatus; perinuclear region of cytoplasm; and spindle pole. Is expressed in several structures, including eye; gonad; jaw bone; thoracic segment skeleton; and unsegmented mesenchyme. Orthologous to several human genes including GOLGA2 (golgin A2).
