Fig. 1. The conserved domains and position on the phylogenetic tree of chick Pcl2
protein. (A) Chick Pcl2 encodes a putative 595 amino acid residue
protein that contains one Tudor domain (AA:45-100) and two PHD finger domains
(AA:105-147; AA:204-238). (B) Phylogenetic tree generated from known Pcl
proteins from Drosophila, Xenopus, chick, mouse and human using
Clustal method with PAM250 residue weight table.
