Models of nuclear export. (A) Suggested sites of interruption of transport of Npl3p. Mex67p and Mtr4p are positioned inside the nucleus because they both bind RNA and therefore may be needed to constitute an export mRNP. (B) Comparison of the paths of nuclear export in yeast and Xenopus oocytes. Conserved transport element (CTE) RNAs are retroviral mRNAs that include the “conserved transport element.”
