P. marinus has four Dlx homologs.
Comparative sequence alignment of the homeodomains of P. marinus
DlxA, DlxB, DlxC, and DlxD with those of murine
Dlx1, Dlx2, Dlx3, Dlx5, Dlx6, and Dlx7.
Residues that match the consensus are boxed. Full-length cDNAs were
isolated from an embryonic P. marinus cDNA library by a
combination of PCR with degenerate oligonucleotides and
hybridization.
