title: Cell-free processing of nascent proteins destined to be linked to the plasma membrane by a phosphatidylinositol-glycan anchor.
abstract: Certain proteins are anchored to the outer plasma membrane by a phosphatidylinositol-glycan (PI-G) linker. Nascent forms of PI-G anchored proteins contain both NH2- and COOH-terminal signal peptides. The function and structural requirements of the COOH-terminal signal peptide as discussed and some studies on the cell-free processing of a nascent protein to its mature PI-G tailed form are presented.
