From: Low nuclear body formation and tax SUMOylation do not prevent NF-kappaB promoter activation
Description of the Tax-P79AQ81A mutant. Schematic representation of the primary amino-acid sequence of Tax showing the N-terminal nuclear localization signal (NLS, amino-acids 1–50), the Tax speckled structure localization signal (TSLS, amino-acids 50–75) and the potential TRAF-binding motif (boxed) in which alanine substitutions were introduced (Tax-P79AQ81A mutant). The lysine residues targeted by ubiquitination and SUMOylation are also indicated.
