摘要

The present invention provides novel methods of treating pain comprising administering to a mammal in need of such treatment an effective analgesic amount of a peptide having the amino acid sequence of SEQ ID. NO.: 1 or SEQ ID NO: 2. The invention further provides a purified peptide having the amino acid sequence of SEQ ID NO: 1. The peptides of SEQ ID NO.:1 and SEQ ID NO.: 2 can also be used in methods for identifying compounds having analgesia-inducing activity.
