Myosin-dependent junction remodelling controls planar cell intercalation and axis elongation:
Article Abstract:
The mechanism by which an ordered process of cell intercalation directs polarized epithelial moephognesis during germ-band elongation, the developmental elongation of the Drosophila embryo is presented. Myosin II is specifically enriched in disassembling junctions, and its planar polarized localization and activity are required for planar junction remodeling and cell intercalation.

Spatial control of actin organization at adherens junctions by the synaptotagmin-like protein Btsz
Article Abstract:
An additional pathway that organizes actin filaments in the apical junctional region (AJR) where adherens junctions form in embryonic epithelia is identified. This pathway is controlled by Bitesize (Btsz), a synaptotagmin-like protein that is recruited in the AJR independently of E-cadherin and is required for epithelial stability in Drosophila embryos.

Caught in the traffic
Article Abstract:
Enzymes like Rab GTPases are crucial controllers of polarized membrane trafficking and causes villus inclusion disease by forming the apical surface in epithelial cells. The analysis provides a better understanding of the acquisition and maintenance of epithelial polarity, cancer and intestinal disease.
