WebbTat acetylated at K28 can activate Tat activity and enhance its ability to stabilize microtubules, thereby enhancing the reverse transcription activity of HIV-1 and promot-ing viral proliferation. Our results showed that LEF-11 acetylation was beneficial for viral proliferation and deacetylation was not conducive to the interaction with IE-1. WebbThis charge neutralization weakens the binding of DNA to histones causing the DNA to unwind from the histone proteins and thereby significantly increases the rate of transcription of this DNA. Many corepressors can recruit histone deacetylase (HDAC) enzymes to promoters.
