The phosphoprotein with increased expression level was identified as dihydropyrimidinase-related protein 2, and 2 phosphoproteins with decreased expression level were identified as proteasome subunit alpha type-3 and beta-soluble NSF attachment protein (Table 2).
We employed a combination of biochemical and histological techniques to test the hypothesis that the barnacle adhesive interface contains phosphoproteins. Specifically, we aimed to identify phosphoproteins in uncured barnacle glue and to determine their location within the barnacle adhesive interface, using residual glue deposited by reattaching barnacles and decalcified barnacle base plates.
A total of 1,645 phosphoprotein groups were identified by scaffold software across all six TNBC cell lines, using peptide probability thresholds of 95% with a minimum of one unique peptide (Figure 1(a)).

Tissue lysates were immunoblotted, and total protein and phosphoprotein levels of Syk, IKK, I[kappa]B [alpha], p65, and [beta]-actin were determined, as previously reported [44, 45].
Of 55 metabolic phosphoproteins, the top two pathways are ribosome and focal adhesion pathways [Figure 3].
They selected 88 antibodies that recognize proteins and phosphoproteins involved in a variety of cancer cell functions such as kinase signaling, epithelial-mesenchyme transition, apoptosis, and autophagy.
Both isozymes are known to be phosphoproteins in vivo.

Such associative behavior of other biomineral proteins such as dentin phosphophoryn, as well as other polyanionic proteins such as casein, has been reviewed by Marsh (1989a, b), who also observed agglomerations of phosphoproteins and mineral salts including amorphous calcium phosphate in nonmineralizing compartments of some molluscs (Marsh and Sass, 1983, 1984, 1985).
