Fig. 8From: Proteomic analysis of quail calcified eggshell matrix: a comparison to chicken and turkey eggshell proteomesComparison of phosphorylation sites in quail and chicken osteopontin. Phosphorylated amino acid residues of eggshell osteopontin are highlighted by yellow shading. Phosphorylation sites identified in metabolically 32P-labeled chicken osteoblast osteopontin [92] are underlined Back to article page
