Bretscher's main contributions lie in the areas of the mechanism of
protein biosynthesisProtein biosynthesis is the process in which cells build or manufacture proteins. The term is sometimes used to refer only to protein translation but more often it refers to a multi-step process, beginning with amino acid synthesis and transcription of nuclear DNA into messenger RNA, which is then...

) and in how animal cells move. He is the principal protagonist of the
membrane flowMost animal cells take up portions of their surface plasma membranes in a process called endocytosis. The main route of endocytosis is the coated pit, which buds into a cell to form a cytoplasmic vesicle — a clathrin-coated vesicle. The membrane so internalised is processed in a series of...

cap formationWhen molecules on the surface of a cell are crosslinked, they are moved to one end of the cell to form a “cap”. This phenomenon, the process of which is called cap formation, was discovered in 1971 on lymphocytes and is a property of amoebae and all locomotory animal cells except sperm. The...
