Fig. 1From: Molecular, phylogenetic and developmental analyses of Sall proteins in bilateriansOrganization of conserved domains in “Sal-box” containing proteins. Colored ovals represent the zinc-finger motifs. The blue rectangle represents the poly-Q region. The turquoise diamond represents the 12 conserved amino acids at the N-terminal end of the Sall proteins that interact with the HDC NuRD [14]. Protein length range is indicated at the rightBack to article page
