Figure 2.
Shows the number of proteins in UniProt with sulfotyrosines. The left most circle represents the data for all proteins, the center circle represents data for mammalian proteins (i.e. human, mouse, rat, bovine, rabbit), the right most circle represents data for only human proteins. The area of the circles represents the number of proteins in UniProt with known sulfotyrosine sites either through direct evidence by publication or by sequence similarity. The bottom semicircle represents the proteins with direct evidence by publications among these total proteins. Out of the 32 published proteins for humans, (A) 14 of them are localized on the cell membrane, while 18 of them are secreted; while none are found intracellularly either in the cytoplasm or nucleus. (B) Shows the biological processes these 32 proteins are involved in. (C) Shows the molecular functions these 32 proteins perform.
