but the heterozygous progeny produced display major reductions
in viability (Wieschaus and Noell).

baz transcript is detected in early embryos and is expressed in a dynamic pattern during embryonic development. In gastrulating embryos, baz transcript is detected beneath the apical membrane in epithelial cells; later, a similar subcellular localization is detected in epithelial cells of the epidermis. In neuroblasts, expression is detected in a crest in the apical cytocortex (facing the epithelium).
baz protein is detected at the apical cytocortex of epithelial cells such as the cells of the tracheal pit and epidermis. In neuroblasts, the protein is in a submembraneous crescent in the apical cytocortex. Expression is detected at metaphase but not at interphase.
Summary of FlyAtlas Anatomical Expression Data: Expression at moderate levels in the following post-embryonic organs or tissues: adult crop, larval/adult hindgut, larval/adult salivary gland.

baz acts as a permissive factor during cell invasion in the follicle cells. baz function is dispensable fro cell invasion and motility but is required cell-autonomously in mediating cell adhesion within the migrating border cell cluster.
RNAi screen using dsRNA made from templates generated with primers directed against this gene causes a phenotype when assayed in Kc167 and S2R+ cells: binucleate cells.
baz and par-6 proteins are interdependent for their asymmetric localisation at the apical cell cortex of epithelial cells and neuroblasts in the embryo.
Embryos mutant for arm and sdtbaz double mutant embryos have very similar early phenotypes with respect to zonula adherens formation. Results suggest that early stages in the assembly of the zonula adherens are critical for the stability of the polarised blastoderm epithelium.
