The accumulation of PAN depends on the activity of a 79 nucleotide RNA element in the 3’ region, called the ENE (Expression and Nuclear retention Element). As such, a secondary structure is obtained which results in the retention of the RNA in the nucleus and hence the name Nuclear Retention Element. The expression and nuclear retention element (ENE), located ~120 nts upstream of PAN RNA’s polyadenylation site, is essential for this high accumulation in the nucleus (Conrad and Steitz, 2005).
