## Abstract

The present invention provides a method for diagnosing and detecting diseases associated with kidney. The present invention provides one or more proteins or fragments thereof, peptides or nucleic acid molecules differentially expressed in kidney diseases (KCAT) and antibodies binds to KCATs. The present invention provides that KCATs are used as targets for screening agents that modulates the KCAT activities. Further the present invention provides methods for treating diseases associated with kidney.
