Synthesis of plasma membrane proteins during development of Dictyostelium discoideum

Extracellular ATP, ecto‐ATPase and calcium influx in Dictyostelium discoideum cells

“…Such phosphorylation may be involved in membrane permeability and transport, cell movement, and the activation of cyclic AMP receptors which occurs during early differentiation [4]. External ATP induces cell aggregation, decreases the chemotactic sensitivity of cells to a cyclic AMP gradient and inhibits intercellular contact sites outside the aggregation center [ 1,5].…”

Isolation and characterization of nuclear envelope fragments from dictyostelium

“…Pore complexes need not constitute the sole passageway of molecular movement between the nucleus and the cytoplasm. The developmentally-regulated plasma membrane glycoproteins [32], some of which have been implicated in cellular adhesion ]33-351, are not found in the nuclear membranes of differentiating cells (unpublished). Specific nuclear glycoproteins are synthesized during D. dj~co~~~ differentiation (unpubh~ed) and it will be interesting to relate changes in nuclear envelope ~om~sition to differentiation.…”

A monoclonal antibody that interferes with the post‐aggregation adhesion of Dictyostelium discoideum cells

“…One-dimentional polyacrylamide gel electrophoresis and Western blotting were carried out as previously described [7,31]. Rainbow molecular weight markers (Amersham), which are conjugated to dyes.…”
