DAYSLEEPER structure and deletions. DAYSLEEPER is 696 amino acids long and has a NLS, a BED zinc finger and hAT blocks. The hAT blocks are located at the following positions: Block A: 231–243, B: 333–345, C: 397–406, D: 607–617, E: 621–645, F: 647–674. Three shortened coding sequences are displayed, which are deleted at either the N-terminus (Δ1-142), the central part (Δ149-589), or the C-terminus (Δ478-665). Sizes of the coding sequences of different constructs are shown, as well as the position of deletions.
