  • a First 56 nucleotides deduced from comparison of left and right inverted repeats.

  • b Protein deducted after correction of frame shifts and stop codons.

  • c Presence of direct repeats within the long inverted repeats but with different properties.

  • d Protein deduced by Brezinsky et al. (1990).

  • e Based on the cDNA identified by Vos et al. (1993).

  • f Protein deduced by Henikoff and Plasterk (1988).
