Ctr9 is a subunit of the Paf1 complex The STAT3-Ctr9 interaction is highly significant for pluripotency of mESCs since Ctr9 indirectly induces multiple histone modifications, including trimethylation of Lys4 and Lys36, dimethylation of Lys79 on histone H3 and ubiquitination of histone H2B, all of which are important for gene activation ( 53 ).
