Interactions between three common subunits of yeast RNA polymerases I and III.

Proceedings of the National Academy of Sciences of the United States of America - 15 Jun 1993

Lalo D, Carles C, Sentenac A, Thuriaux P

Abstract excerpt

The AC40 and AC19 subunits (encoded by RPC40 and RPC19) are shared by yeast RNA polymerases I and III and have a local sequence similarity to prokaryotic alpha subunits. Mutational analysis of the corresponding "alpha motif" indicated that its integrity is essential on AC40 subunit but is not essential on AC19 subunit. By applying the two-hybrid method, these two polypeptides were shown to associate in vivo....
