Brings together studies from the disciplines of Drosophilia genetics, Xenopus development, cell biology, and oncology, focusing on structural and signal transduction aspects of components of cell junctions, regulatory aspects of inside-out and outside-in signalling at cell junctions, and the role of patterning genes in early development and in the histogenesis and pathology of the skin and the colon. Topics include cadherins and the catenin adaptors, plakoglobin, the Wnt signaling pathway, and ERM proteins. Annotation c. by Book News, Inc., Portland, Or.
