A mutation altering the function of a carbohydrate binding protein blocks cell-cell cohesion in developing Dictyostelium discoideum.

abstract：:The cell adhesion molecules L1, N-CAM and Ng-CAM have been implicated in cell-cell interactions among developing neural cells. L1 and N-CAM are structurally and functionally distinct molecular entities and act synergistically in mediating Ca2+-independent adhesion between re-aggregating early postnatal cerebellar cell...

abstract：:The sequence-specific DNA-binding protein, MyoD, can activate muscle-specific gene expression in some cells in culture. Xenopus MyoD (XMyoD) transcription is activated as a consequence of mesoderm induction in the early myotomes, from which the axial musculature develops. XMyoD RNA accumulates about two hours before m...
