| Outline of Final Research Achievements |
We identified a Gtf2i splice variant mRNA that is specifically localized at the postsynaptic sites. We also identified in the brain four proteins that interact with a limitted sequence in the 5'UTR of postsynaptically localizing Gtf2i mRNA. Then we studied mechanism(s) for regulation of local protein synthesis of the Gtf2i protein at the postsynaptic sites. Our experiment suggests that expression of postsynaptically localized Gtf2i proteins are under control of multiple protein factors at the postsynaptic site via interaction with 5'UTR of postsynaptically localizing Gtf2i mRNA.
