Cell-cell adhesion is a critical property of all multi-cellular organisms and its correct regulation is critical during development, differentiation, tissue building and maintenance, and many immune responses. The multi-talin-like FERM domain containing protein, FrmA, is required during starvation-induced multi-cellular development of Dictyostelium cells. Loss of FrmA leads to increased cell-cell adhesion and results in impaired multi-cellular development, slug migration and fruiting bodies. Further, mixing experiments show that FrmA null cells are excluded from the apex of wild-type mounds, to which cells that normally form the organising centre known as the tip sort. These data suggest a critical role for FrmA in regulating cell-cell adhesion, multi-cellular development and, in particular, the formation of the organising centre known as the tip.
