Résumé :

The poly(A)‐binding protein P38 of non‐polysomal mRNP from Artemia salina gastrulae was labelled by reductive methylation and microinjected into he cytoplasm of Xenopus laevis oocytes. The labelled protein has a half‐life of approximately 20 h and accumulated in the nucleus to a final concentration 3.15 timees higher than that reached by free diffusion. This fact suggests that P38, a cytoplasmic poly(A)‐binding protein, might also play some role in the nucleus of the cell. Copyright © 1983, Wiley Blackwell. All rights reserved
