Endocytosis occurs when the cell membrane engulfs particles (dark blue) outside the cell, draws the contents in, and forms an intracellular vesicle called an endosome. This vesicle travels through ...

This takes place when molecules diffuse across the cell membrane by travelling through specific transport proteins. It occurs down a concentration gradient - molecules move from an area of high to ...

Most of the proteins with SH3 domains are adaptors that link WASP and WAVE proteins to other proteins or the cell membrane. The Bin, amphiphysin, Rvs167 (BAR) and extended Fer-CIP4 homology (EFC ...
