dc.descriptionCrawling is a fundamental form of locomotion in many eukaryotic cells. Perhaps the most-often studied example is that of the giant freshwater protist, Amoeba proteus. The cell extends large, blunt pseudopodia. These protrusions contain a marginal zone of clear cortical cytoplasm called the ectoplasm, which is more gel-like. This surrounds the inner, fluid endoplasm. Within this fluid cytoplasm numerous organelles, including mitochondria and vacuoles, can be seen to stream. Endoplasm moves into regions of new pseudopodial extension, and out of regions where pseudopodia are retracting. As these movements occur, interconversions of cytoplasm between ecto- and endoplasm are continually occurring. These sol-gel transformations leading to cellular migration involve actin-
