Polypeptides Having Brain-Localizing Activity and Uses Thereof

摘要

DNAs encoding polypeptides comprising random amino acid sequences were synthesized, and incorporated into a phage library. The phage library produced was used to screen for polypeptides having brain-localizing activity. As a result, several polypeptides having brain-localizing activity were obtained. These polypeptides comprise common sequences, and amino acid motif sequences involved in brain-localizing activity were successfully identified.
