Figure 12From: Ancient, independent evolution and distinct molecular features of the novel human T-lymphotropic virus type 4Comparison of predicted amino acid sequences of primate T-cell lymphotropic viruses and cellular basic leucine zipper (bZIP) transcription factors. Conserved arginine rich and potential leucine zipper regions of the bZIP proteins are boxed. Alternate amino acid sequence resulting from frameshift mutation in HTLV-2(MoT) leucine zipper region is shown in italics.Back to article page
