title: A GAP in convergent extension scores PAR.
abstract: The process of "convergence and extension" regulates cellular intercalation during gastrulation. An ArfGAP-PAR protein complex is required for the associated cellular polarization. Potential interactions between this complex and relevant planar cell polarity factors in this context are discussed.
