LARKS and LCDs of proteins in six analyzed proteomes. The center of each donut chart gives the percentage of proteins in the proteome that have an LCD and is represented by the black arc in the inside of the donut chart. The outer ring of the donut chart shows the percentage of proteins that are LARKS rich with an LCD (dark blue: LARKS ∩ LCD), just LCD-containing (light blue: LCD), LARKS rich without having an LCD (dark green: LARKS ∩ non-LCD), or non-LCD–containing (light green: non-LCD). The integers listed next to the keys give precise values for the number of proteins in each category for their respective proteomes. LARKS, low-complexity amyloid-like reversible kinked segment; LCD, low-complexity domain.
