May belong to a complex set of multifingered proteins which play an important role in gene activation or regulation at early embryonic stages through a maximal accumulation of their transcripts (or protein product) in the mature oocyte. Distribution varies between nurse cells and the oocyte during oogenesis. Weakly expressed in follicle and border cells. Expressed both maternally and zygotically. Expressed from stage 1 of oogenesis. Expressed at a low level in the embryo from the tenth nuclear division to the end of cellularization in all cell nuclei except those of pole cells. Also weakly expressed in the embryo after germ-band retraction, and in larvae (at protein level).
