Protein encoded by the exuperantia gene is concentrated at sites of bicoid mRNA accumulation in Drosophila nurse cells but not in oocytes or embryos.

Genes & development - 1 Dec 1991

Abstract excerpt

Formation of the anteroposterior gradient of the bicoid (bcd) protein morphogen in Drosophila occurs as a consequence of the prelocalization of bcd mRNA to the anterior pole of the oocyte. bcd mRNA localization requires at least three genes, with the exuperantia (exu) gene acting earliest in the pathway. We have cloned and characterized the exu gene. Notably, we find that exu protein is colocalized with bcd mRNA...
