BCL9 cDNA sequence (Y13620) together with predicted amino acid translation. (i) Breakpoint in CEMO-1 in theBCL9 3' UTR is indicated by a solid arrow. (ii) Polyadenylation sites are underlined. (iii) Potential nuclear localization signal is indicated by shaded box. (IV) Region with strong (90%) amino acid homology to Drosophila embryo EST (accession no.AA202331) is underlined. Outside this region, the EST lacked homology with BCL9. (v) Pentapeptide repeats are indicated by open boxes (sequence with residue numbers in parentheses): SPSGN (11-15, 35-39, 878-882)(; SSTPL (294-298, 1020-1024); SSTP (988-992, 1019-1023); and QGMMG (1274-1278, 1324-1328, 1385-1389).
