Mediates the nuclear export of actin and profilin-actin complexes in somatic cells. Oocyte nuclei lack active actin export. Shuttles between the nucleus and the cytoplasm. Expressed during meiotic maturation 2 hours after germinal vesicle break down (GVBD) and in unfertilized and fertilized eggs, but not in oocytes (at protein level). Expressed in somatic cells, in oocytes, during meiotic maturation and in unfertilized and fertilized eggs. Expressed in embryo at 8, 12 and 30 hours post-fertilization (hpf). Belongs to the exportin family.
