Source of sequence: The sequence was identiﬁed by searching dbEST for putative zinc ﬁnger patterns from
Arabidopsis thaliana. The clone (229I5T7) was obtained from the Arabidopsis Biological Resource
Center, Ohio State University.
Name: PMZ, a cDNA from Arabidopsis thaliana encoding a putative, novel zinc ﬁnger motif with
homologues in invertebrates and mammals.
Description: The open reading frame encodes 186 amino acids, with two putative novel C
C zinc ﬁnger
motifs, followed by a C-terminal serine-rich sequence of 40 amino acids. The two C
C motifs are
separated by a sequence containing a C
HC motif, and a highly basic region.

Figure 1. Alignment of Arabidopsis PMZ with translated genomic and EST sequences from other organisms. Hs, Homo sapiens (EST
AA449622); Dm, Drosophila melanogaster (EST AI238366); Ce, Caenorhabditis elegans (Gene F58E10.4); At, Arabidopsis thaliana PMZ;
Le, Lycopersicon esculentum (EST AI486585). Residues conserved or chemically similar in 50% or more of the sequences are surrounded by
black and grey, respectively. The 8 completely conserved putative zinc ligands in the two repeated motifs are indicated by numbers 1–8. Three
cysteines and a histidine that are possibly part of a third zinc-binding motif are marked by asteriks. ...Indicates a highly basic region, typical
of protein localized to the nucleus.
