Biological Data

Biological description

Stimulator of the homologous recombination protein hRAD51. Enhances the DNA binding and homologous recombination activities of hRAD51.


Improves efficiency of HDR (homology-directed repair) 3- to 6-fold (depending on locus and transfection method).

Also enhances Cas9- and TALEN-mediated knock in efficiency in vitro and in vivo. Increases knock-in efficiency in vitro by 2- to 5-fold at different loci and achieves multi-fold improvement in vivo.

Additionally promotes significant anti-tumor responses.
