One of the CBI Molecules being studied in the University of Massachusetts Amherst Chemistry-Biology Interface Program at UMass Amherst and on display at the Molecular Playground.

HIV Tat, or simply Tat, is a human immunodeficiency virus (HIV) gene that regulates transcription of HIV dsRNA. Tat, which stands for trans-activator of transcription, contains 86 amino acid residues in its sequence.

It is released by HIV infected cells in order to enhance replication of the virus. Green and Lowenstein, and Frankel and Pabo independently published studies in Cell in 1988 that showed that Tat had the ability to cross cellular membranes and initiate transcription of HIV dsRNA. This was the first known report of a cell penetrating peptide.

Cell penetrating peptides (CPPs) are proteins with the ability to cross cellular membranes and facilitate the uptake of various cargo, such as small molecules, siRNA, and small DNA fragments. Such cargo can be associated via covalent or non-covalent interactions.
