Phosphophoryn is the most acidic protein ever discovered and has an [[isoelectric point]] of 1. This extreme acidity is achieved by its [[amino acid]] sequence. Many portions of its chain are repeating -D-S-S- ([[aspartate|aspartic acid]]-[[serine]]-serine) sequences. In [[protein]] chemistry, net acidity equates to negative charge. Being highly negative, dentin phosphoprotein is able to attract large amounts of [[calcium]]. ''In vitro'' studies also indicate phosphophoryn can initiate [[hydroxyapatite]] formation.<ref>Nanci, Antonio. Ten Cate's Oral Histology: Development, Structure, and Function. 7th ed.
