The modification of Ser 5 is important for the relocalization of RNAP II upon NaCl stress. The CTD14 strains harbors a plasmid expressing RPB1 with 14 wild-type CTD repeats. The 5A strain carries a plasmid expressing a chimeric RPB1 in which the CTD was composed of 5 repeats of CTD-serine 5 substitu...
