Fig. 10. Comparison of zinc fingers in mouse WT1 and other transcription factors with closely related Krüppel class zinc fingers. Note that WT1 has four zinc fingers, whereas the others have three. WT1 zinc fingers 1-3 align with corresponding zinc fingers in SP1, SP3, MGIF, GKLF and KLF2. EGR1 zinc fingers align with WT1 zinc fingers 2-4. WT1 zinc finger one has distinct amino acids (shown in bold).
