- LexA represor binds specifically to the SOS-box sequence and represses the genes belonging to the SOS regulation. In response to DNA damage, RecA protein is activated by ss-DNA accumulated in the damaged cells and promotes autocleavage of LexA repressor by its coprotease activity. As a result, DNA repair genes and error prone polymerases are induced, and DNA damage is repaired and mutation is induced (1). The lexA gene is used for yeast two-hybrid experiments as a bait to identify the protein-protein interaction in vivo.Alternative names: exrA, spr, tsl, umuA
