“…Sp1 is required by HIV-1 for basal transcrip- tion (36) and can target cyclin T1 to the LTR in the absence of Tat or TAR RNA (37). An increase in Sp1 phosphorylation induced by Tat and DNA-PK can enhance HIV-1 transcription (38).…”

“…The liberated NF-κB then translocates from the cytoplasm to the nucleus and activates the transcription of proinflammatory factors, such as NO, iNOS (4,40). It has been recognized that posttranslational modifications involve the activation of NF-κB, including phosphorylation and acetylation (9,12). O-GlcNAc modifies NF-κB via disrupting its interaction with IκB, which results in translocation of NF-κB into the nuclear and stimulation of NF-κB-dependent gene expression (40,41).…”

“…It has been suggested that O-linked GlcNAcylation and phosphorylation are critical posttranslational modifications (9,12). Many O-GlcNAcylation modified sites are also phosphorylation sites, demonstrating a complex relationship between O-GlcNAcylation and phosphorylation, the so-called 'yin-yang' hypothesis (11,13).…”
