11. Synonyms for this protein include sialoprotein I and 44K BPP ( bone phosphoprotein ). 12. These factors include ENA / VASP ( enabled / vasodilator-stimulated phosphoprotein ). 13. After the phosphate group is transferred, ADP and the new phosphoprotein are released. 14. It is a dual-specificity phosphoprotein phosphatase. 15. Other materials ( such as lipids, phosphoproteins , and phospholipids ) are also secreted. 16. Synapsin I phosphoproteins make up approximately 6 % of the total protein in synaptic vesicles. 17. This gene is located in the calcium-binding phosphoprotein gene cluster on chromosome 4. 18. MUC1 is a member of the mucin family and encodes a membrane bound, glycosylated phosphoprotein . 19. Hsp20 phosphorylation correlates well with smooth muscle relaxation and is one significant phosphoprotein involved in the process. 20. This latter enzyme is itself activated by protein kinase A and deactivated by phosphoprotein phosphatase-1.
