From: Genomic analysis of the TRIM family reveals two groups of genes with distinct evolutionary properties

Figure 1

TRIM domains in evolution. A) Logo representation of the sequences of Plant B-box (60 B-box sequences; representative species: A. thaliana, O. sativa, P. sativum, B. nigra); Metazoan B-box1 (all the B-box1 sequences in representative species: H. sapiens, D. melanogaster, and C. elegans); Mammalian B-box2 (all B-box2 sequences in representative species: H. sapiens) and Invertebrate B-box2 (all B-box2 sequences in representative species: D. melanogaster, and C. elegans). The overall height of each position is proportional to its information content and, within a given position, the conservation of each residue is represented as the relative height of amino acid symbols. Shaded columns indicate the residues involved in the coordination of zinc atoms. Blue bars represent amino acid segments of variable length; the mean value for each segment is reported. Red bars represent segments of fixed amino acid length that are present only in a proportion (indicated in red above the bar) of proteins. B) TRIM complements of humans, fruitfly (D. melanogaster) and worm (C. elegans). The total number of TRIM and TRIM-like genes in each species is indicated (top). The presence of the TRIM associated C-terminal domains is indicated with the same color code (bottom). The length of each bar in the bottom part is proportional to the number (also indicated) of the relative TRIM C-terminal domains found in each species.
