Abstract
This invention relates to a newly identified protein useful for treating diseases of the immune system, methods for obtaining said protein, isolated nucleic acids encoding said protein, and methods for obtaining inhibitors of said protein. The protein of this invention is characterized by an apparent molecular weight of about 32 kD, an isoelectric point of about 4.0-4.5 and coprecipitation with CD45. The protein may also be used in in vitro or in vivo assays to identify inhibitors of T cell activation.
