Abstract：
:In vitro synthesis of myelin proteolipid protein (PLP) was explored at different ages using rat brain total homogenates, incubated for 30 min with [3H]glycine. Total proteolipids, extracted from the incubated samples, were separated by SDS-PAGE and the radioactivity was measured in the band corresponding to myelin PLP. The incorporation into PLP in relation to the incorporation into brain total proteins increased from 0.04% at 10 days of age to 0.63% at 20 days, and declined slowly thereafter. Time course experiments were carried out using brain homogenates obtained from rats of 20 days of age (i.e. at the period of maximal synthesis of PLP). Labeled PLP molecules were already found at 2.5 min of incubation and the incorporation of the label into this protein, relative to the incorporation into total proteins, did not vary throughout the entire incubation time (30 min). Pulse-chase experiments using a similar system and adding cycloheximide at different incubation times showed that the appearance of label into mature PLP was immediately blocked by the inhibitor of protein synthesis. These data suggest that PLP is synthesized as such and not as a pre-protein which is subsequently processed to render mature PLP.
