Endocytosis, Capping and Cell Locomotion Directed lipid flow in cell membranes. Capping of Exogenous Forssman Glycolipid on Cells. This paper establishes that glycolipids, inserted into the outer monolayer of a motile cell and then cross-linked with antibodies, can cap. It implies that capping does not require direct interaction with cytoplasmic factors. Lateral Diffusion in eukaryotic cell membranes.
Coated pits act as molecular filters.
It is shown that some surface proteins are excluded from plasma membrane coated pits as they bud into the cell. Therefore, as far as these noncirculating proteins are concerned, any effects that the endocytic cycle might have upon them would be seen as a lipid flow. Membrane recycling by coated vesicles.
