Utant that we had earlier observed associating with ESCRT-I, the YLPM1 associated proteins, and CPSF6/7. When we purified Halo-TNIP2 196 ?46 associated proteins in the presence of Benzonase? an endonuclease that digests both DNA and RNA, we detected the bait proteins shown in Fig. 5A (light gray bars). There was no significant change in the relative amounts of the subunits of the ESCRT-I complex d
