Formation and maintenance of a polarized microtubule array originating from a microtubule-organizing center (MTOC) in the oocyte. The MTOC nucleates a microtubule network that extends through the ring canals into the 15 nurse cells of the cyst.

The apical end of the lateral plasma membrane of epithelial cells.

The membranes on the sides of epithelial cells which lie at the interface of adjacent cells.

The process of introducing a phosphoric group into a molecule, usually with the formation of a phosphoric ester, a phosphoric anhydride or a phosphoric amide.

The process of removing one or more phosphoric (ester or anhydride) residues from a molecule.

Catalysis of the removal of one of the two phosphate groups of an inositol bisphosphate.

Catalysis of the reaction: phosphatidylinositol-3,4,5-trisphosphate + H2O = phosphatidyl inositol-4,5-bisphosphate + phosphate.

Catalysis of the reaction: 1-phosphatidyl-myo-inositol 3,4-bisphosphate + H2O = 1-phosphatidyl-1D-myo-inositol 3-phosphate + phosphate.

The process by which photoreceptors are arranged in ommatidia in the dorsal and ventral fields to be mirror images. The polarity is established in the imaginal discs concurrently with cell fate specification.

The process whose specific outcome is the progression of the mushroom body over time, from its formation to the mature structure. The mushroom body is composed of the prominent neuropil structures of the insect central brain, thought to be crucial for olfactory associated learning. These consist mainly of a bulbous calyx and tightly packaged arrays of thin parallel fibers of the Kenyon cells.

Interacting selectively with a steroid, any of a large group of substances that have in common a ring system based on 1,2-cyclopentanoperhydrophenanthrene.

The binding of a cell to the extracellular matrix via adhesion molecules that require the presence of calcium for the interaction.

Interacting selectively with any androgen, male sex hormones.

Complex of peripheral cytoplasmic proteins (alpha-, beta- and gamma-catenin) that interact with the cytoplasmic region of uvomorulin/E-cadherin to connect it to the actin cytoskeleton.
