Research Abstract

To make clear the molecular mechanisms of Fyn tyrosine kinase-mediated regulation of neural morphogenesis, I focused on TCGAP, one of Fyn substrates in the central nervous system. By analyzing TCGAP KO mice, I found that TCGAP regulated intracellular trafficking, spine morphogenesis, and dendrite morphogenesis. Together with the finding that TCGAP KO mice showed several behavioral abnormalities, Fyn-mediated phosphorylation of their substrates including TCGAP and p250GAP is necessary for higher brain functions.
