alternative splicing seems to regulate TdT isoform expression. Both long isoforms, hTdTL1 and hTdTL2 have 3'-5' exonuclease activity. Overexpression of the short isoform hTdTS or the long isoform hTdTL2 greatly reduces the efficiency of recombinantion, which is reverted to normal levels by simultaneous expression of both enzymes
