The technology described herein relates to controlled chemically- or light-induced rejoinder of split-recombinases. In some embodiments, compositions, methods, kits and systems are provided that relate to a split-recombinase system, whereby protein complementation or rejoinder of split-recombinases is mediated by chemical-induced dimerization domains (CIDDs) or light-induced dimerization domains (LIDD) and rejoinder of the split-recombinases occur in the presence of one or more chemical inducers or light inducers, respectively. The split-recombinases systems as disclosed herein can be used in gene therapy, integrated logic and memory in living cells such as mammalian cells. The nucleic acid cassettes, switches, and systems described herein allow for controlled gene expression or gene regulation. The controlled chemically- or light-induced rejoinder of split-recombinases can be used in, for example, adopted T-cell therapy.

Inducible dimerization of recombinases

The invention provides, inter alia, recombinase-based systems that provide for integrated logic and memory in living cells such as mammalian cells. The nucleic acid cassettes, switches, and systems described herein allow for control of gene expression or gene regulation. The invention also provides nucleic acid-based switches for adopted T-cell therapy.
