Synthesis in vitro and translocation of apolipoprotein AI across microsomal vesicles.

Abstract

Apolipoprotein AI of rats has been synthesized in a cell-free wheat germ system and cotranslationally translocated into dog pancreas microsomal vesicles. Translocation is accompanied by cleavage of a signal sequence of 18 amino acid residues and is dependent on the recently purified signal recognition protein.
