TAT-Apoptin

Codes for the T7 expression cassette for Apoptin composed of a N-terminal TAT translocation peptide, followed by a linker (GGGGS), a histidine tag (6x) and by the same linker fused to Apoptin. Apoptin, also called VP3, is a protein from the Chicken Anemia Virus (CAV) known to cause p53-independent apoptosis in more than 70 human cancer cell lines while leaving normal cells unharmed.

Apoptin contains a bipartite nuclear localization signal (NLS1: aa 82-88 and NLS2: aa 111-121) and a nuclear export signal (NES) (aa 97-105). In cancer cells, Apoptin localizes to the nucleus while in normal cells it's found in the cytoplasm; it is thought that the bipartite NLS is activated by phosphorylation at Threonine 108 which only happens in cancer cells.
