From: Dissecting the role of low-complexity regions in the evolution of vertebrate proteins
Relative abundance of low-complexity regions (LCRs) at different phylogenetic depths. The area of the circles is proportional to LCR relative frequencies. The number of LCRs at each branch is indicated. In black, data for all LCRs. In blue, data for LCRs enriched in positively charged amino acids (K and R). In red, data for LCRs enriched in alanine (A), glycine (G) or both. The LCR phylogenetic distribution of LCRs labeled in blue, and of LCRs labeled in red, deviated significantly from the expected one considering all LCRs (Fisher’s exact test p < 10-5).
