Cellularization of the early Drosophila embryo is a modified form of cytokinesis that gives rise to the blastoderm epithelium through polarized membrane growth. The gene slow-as-molasses encodes a novel protein essential for the formation of a plasma membrane domain that initiates membrane growth during cellularization.
