tRNA-splicing endonuclease subunit Sen2 is an enzyme that in humans is encoded by the TSEN2 gene.^[5]^[6]

tRNA splicing is a fundamental process required for cell growth and division. SEN2 is a subunit of the tRNA splicing endonuclease, which catalyzes the removal of introns, the first step in tRNA splicing (Paushkin et al., 2004).[supplied by OMIM]^[6]
