Does not appear to be a mRNA-cap-binding protein. Ovary, muscle and testis. Expressed both maternally and zygotically. Levels decrease on oocyte maturation, increase during the midblastula transition, then decline again and are lost by 24 hours post-fertilization (hpf). Uniform distribution during gastrulation, but later becomes concentrated in mesodermal lineages, particularly those located ventrally.
