Amino acid sequence of CCM1 protein. (A) Predicted amino
acid sequence of CCM1 is shown as one-letter symbols. A putative
zinc-finger motif is highlighted and a Gln-repeat region is italicized.
The His residue at position 54, which is changed into Tyr in the
cia5 mutant, is depicted as His-54. Asp-183 and Arg-184
and a Gly-rich region are underlined. (B) Sequence
comparison of the putative zinc-finger motif of CCM1 with zinc-finger
motifs in other organisms: Homo sapiens (Hom) ZNF76
(NM_003427), Xenopus laevis (Xen)
TFIIIa2 (K02938), Drosophila melanogaster (Dro) ZFH2
(P28167), Dro Krüppel (X03414), Petunia hybrida
(Pet) EPF1–1 (X60700), and Triticum aestivum (Tri) WZF1
(D16415). Filled circles denote zinc-liganding amino acids. Conserved
amino acids are highlighted.
