Zinc transporter foi

Gene

foi

Organism
Drosophila melanogaster (Fruit fly)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Required for the normal migration of longitudinal and peripheral glial cells. During larval development, required for the migration of the subretinal glia into the eye disk. During embryonic development, also controls the migration of muscle cells toward their attachment sites. Required in the mesoderm for the correct morphogenesis of embryonic gonad and for tracheal branch fusion during tracheal development. Shg may be cooperating with foi to mediate a common mechanism for gonad and tracheal morphogenesis. Acts as a zinc transporter in both yeast and mammalian cells.3 Publications

Expressioni

Tissue specificityi

Maternal foi has almost completely disappeared by embryonic stage 3 except in the pole cells. In stage 6 embryos, expression is enriched in the invaginating mesoderm. In stage 9 embryos, high levels in the anterior and posterior midgut primordia. In stage 14 embryos, broad expression with low levels in the epidermis.1 Publication
