Novel protein, process for producing the same and use thereof

摘要

The present invention is intended to provide a novel protein, specifically to provide a protein comprising the same or substantially the same amino acid sequence as that represented by SEQ ID NO: 1 or a salt thereof; a DNA encoding the said protein; a medicament comprising the said protein or DNA; and a method of screening for a compound capable of enhancing or inhibiting the peptidase activity of the said protein. The protein of the present invention and the DNA encoding the same can be used as a therapeutic and/or prophylactic agent for cancers or neurodegenerative diseases. The protein of the present invention and cells capable of expressing the gene of the said protein are useful as a material for screening for a compound or a salt thereof capable of enhancing or inhibiting the peptidase activity of the said protein.
