Analysis of ZAR2 protein sequence. (A) Amino acid sequence of human ZAR2 protein showing the C4 type zinc fingers. Cys residues of the zinc fingers are underscored and putative nuclear localization signals are highlighted. (B) CLUSTALW alignment between human ZAR1 (NP_783318) and ZAR2 (NP_001130043) amino acid sequences. hZar1: human ZAR1; hZar2: human ZAR2. Identical amino acid residues are highlighted in grey and the similar amino acid residues are shown in yellow shades. The conserved C4-type zinc fingers #1 and #2 are also shown.
