Required to regulate pattern formation during multi-cellular stages of development and for the formation of adherens junctions. Plays a structural role during the regulation of stalk formation. Involved in cell signaling. Required for spore-cell differentiation. Overexpression increases number and size of cell junctions and reduces spore-cell formation. Localized at the cell junctions in the developing fruiting body. Complete loss of cell junctions. Lacks actin-containing adherens junctions at the top of the stalk tube. Has weak stalks causing the fruiting body to frequently collapse. Displays multiple stalks appearance during late development. Shows no defects in growth or division. Belongs to the beta-catenin family.
