Sequence comparisons of

BCL11A, Evi9, and BCL11B. (A) Comparison ofBCL11A, previously isolated mouse Evi9 isoforms, and BCL11B. C₂H₂ zinc fingers are denoted by shaded boxes, the acidic region is denoted by a hatched box. The positions of the first and last amino acids of C₂H₂ zinc fingers are shown underneath. Note lack of last 3 zinc fingers in the longest mouse Evi9isoform and close similarities in the overall structure ofBCL11A_XL and BCL11B. (B)BCL11A isoforms. Proteins of 835 (BCL11A_XL, accession no. AJ404611), 773 (BCL11A_X, accession no. AJ404612), and 243 (accession no. AJ404613) amino acids resulting from the common alternative splices. Dots represent identical amino acid residues.
