Fig. 1. FOI is a member of the ZIP family of zinc transporters. (A)
Diagram of the FOI protein with conserved domains highlighted. Mutations
introduced into HA-FOI are specified. (B) Sequence alignment of highly
conserved domains (as indicated) of representative ZIP proteins from different
subgroups. Adapted, with permission, from Mathews et al.
(Mathews et al., 2005).
Alternative nomenclature for these same proteins is included in the lower
alignment. Residues tested for function in gonad morphogenesis are indicated
(brackets link mutations introduced together). (C) Deconvolution images
of Drosophila S2 cells transfected with the indicated
UAS-foi constructs and immunolabeled with
-HA (red) before
permeabilization. DAPI (blue) labels the nuclei. Scale bar: 10 µm.
