Membrane transport in the endocytic pathway: Animal versus plant cells

2000

The endocytic pathway is a well established process in animal cells, but it is not well understood in plant cells. At the morphological level, all the compartments involved in endocytosis in animal cells seem to have counterparts in plant cells, and the organization of the pathway appears to share some striking similarities. Several Rab homologues have been found in plant cells, including homologues of Rab5, Rab7, and Rab11, markers of endocytic compartments in animal cells. Coat proteins are also present in plant cells, including clathrin, adaptins, and ADP ribosylation factor proteins. However, endocytic compartments in plant cells also exhibit specific features both in organization and f…
