The SB transposase is an active transposase reconstructed from consensus sequences of several mutated and inactive Tc1/mariner family transposase genes in salmonid fish. The transposase is an element of a transposon that catalyzes the excision of transposon DNA from its original location and promotes its reintegration elsewhere in the genome.
