Proteins Unaffected by Adenovirus Infection-We also thought it a relevant control to examine a protein that did not apparently change in nucleolar abundance by 18 h postinfection. Nop132 is thought to help recruit dead box protein DDX47 to the nucleolus and therefore play a role in rRNA processing (48) . As can be seen in Fig. 6 , there is no apparent change in the pattern of distribution of Nop132 at the time examined.
