Description | Tag derived from the transactivating (Tat) protein of human immunodeficiency virus 1 (HIV-1) that can enter cells efficiently when added exogenously in tissue culture. The Tat tag can carry other molecules into cells, by fusion of Tat peptides (residues 1-72 or 37-72,) to any molecule under study. Tat-mediated uptake may allow the delivery of macromolecules previously thought to be impermeable to living cells. | Namespace | PSI-MI |
