In episode #2 of GuidePost, Kevin Davies (Executive Editor, The CRISPR Journal) travels to Lithuania to meet Virginijus Šikšnys, one of the central figures in the development of CRISPR gene editing, at his lab at the Institute of Biotechnology, Vilnius University. Siksnys is an expert in DNA-protein interactions, and in 2011-12, made critical contributions in transferring the Cas9 enzyme into E. coli and characterizing the mechanism by which it cuts DNA.
