I found three novel phosphorylation sites in mice and three in primates, including humans in growth-associated protein-43 (GAP-43), by using Phosphoproteomics. GAP-43 is considered to be a nerve growth and regeneration factor. While analyzing the function of GAP-43, I am conducting research aiming at clinical application to humans. On the other hand, in clinical practice, I specialize in pituitary tumors and suprasellar tumors. I am analyzing them using molecular approach.
