Figure 2From: PHOSIDA (phosphorylation site database): management, structural and evolutionary investigation, and prediction of phosphositesAccessibilities of phosphorylation sites as calculated by SABLE. The relative accessibility prediction assigns a value between 0 (fully buried) and 9 (fully exposed) to each residue. For phosphoserines, phosphothreonines and phosphotyrosines, accessibility is significantly higher than for their non-phosphorylated counterparts in the same proteins.Back to article page
