Usage and Biology

LexA binding domain - VP16 activation domain is a synthetic transcription factor. LexA Binding Domain is a sequence in the LexA protein, a transcriptional repressor (Zhang et al., 2010) of the SOS regulon in Escherichia coli that allows the binding of different regulatory molecules (Thliveris & Mount, 1992). VP16 is a transcription factor from herpes simplex virus (HSV) type 1 that is involved in the activation of the viral immediate-early (IE) genes (HIRAI et al., 2010). The N-terminal region of the protein confers specificity for the IE genes, whilst the C-terminal part contains two functional regions, VP16ad/c and VP16ad/n, that are required for transcriptional activation (Jonker et al., 2005). It was acquired from the DualMembrane Kit 3 (Thaminy et al., 2003).
