SF   bind to minor groove of a Watson-Crick double helix by recognizing the WWCAAAG [4];
SF   multitude of TCF-1 proteins from 25 to 55 kDa due to structure of TCF-1 gene: 2 alternative upstream promoters, presence of 13 exons (Ia', Ib', I, II, IIa, III, IV, IVa, V, VI, VII, VIII, IX, X) and existence of a second reading frame in the last exon encoding an extended C terminus [4];
SF   a total of 96 different mRNAs is possible;
SF   high similarity to lymphoid factor LEF-1, mouse TCF and chicken TCF;
SF   alternative exon IIa coding for ERKCSPREGUDWPRILQUK, insertion of this exon between exon II and III will result in the production of a 16-kDa protein lacking DNA-binding properties [5];
