Nuclear and polyribosomal ribonucleoprotein particles containing poly (A) in rat liver cells.

T Tomcsanyi, J Molnar, A Tigyi.   

Abstract

Poly(A) containing ribonucleoprotein particles were prepared from rat liver nuclei and polyribosomes. The particles have sedimentation coefficients of 14 S and 9 S, respectively. In CS2SO4 density gradients the particles banded at densities of 1.28-1.29 g cm-3. Both nuclear and polyribosomal poly(A)-RNP contain in addition to some minor polypeptides, two main polypeptides having molecular weights of 63 000 and 90 000 dalton, respectively indistinguishable from each other according to their electrophoretic mobilities.
