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 brain; eye; gonad; musculoskeletal system; and unsegmented mesenchyme. Orthologous to human GOLGA2 (golgin A2).
MGI Description
PHENOTYPE: Homozygotes for a null allele show premature death, developmental delay, ataxia, Purkinje neuron loss, and male infertility with globozoospermia and lack of acrosome formation. Homozygotes for a different null allele show partial prenatal lethality and autophagy-induced liver and lung fibrosis. [provided by MGI curators]
