^aThis region, exhibiting 12 repeat units in Apl2, is about the same length as a typical AT-2 domain. Corresponding repeat units can be detected in the N-terminal regions of many AT-2 domains as revealed in Fig. 1 (horizontal lines at top left of the figure; see legend). The numbers of the 12 C-terminal 7-residue repeats in Apl2 are presented in column 1, while the residue position at the beginning of each repeat is indicated in column 2.

^bThe two dominant residues at each position are presented in the consensus sequences.
