Cre is a DNA recombinase that recognizes 34 base-pair loxP sites of recombination. We have developed a cell-permeable Cre recombinase, TATCre, that is capable of mediating deletion of loxP-flanked targets by simply adding TATCre to cell cultures. Thus, TATCre allows efficient induced DNA recombination without the use of a Cre recombinase transgene or any other genetic material and should prove useful for the genetic manipulation of a wide variety of cell types that have been engineered to possess loxP sites.
