FAZF is similar to PLZF. (A) Comparison of the amino acid sequences of FAZF and PLZF showing BTB/POZ domains (underlined at the amino termini) and zinc fingers (underlined at the C-termini) in CLUSTAL W format. The FAZF sequence has been submitted to GenBank (accession no. AF165097). (B) Schematic representation of the PLZF and FAZF proteins indicating regions of homology and similarity.
