Hermansky pudlak syndrome protein-interacting proteins and methods of use thereof

摘要

The present invention relates to complexes of the HPS protein with proteins identified as interacting with HPS protein by a modified yeast two hybrid assay system. The proteins identified to interact with HPS protein are 14-3-3 protein, Hrs, atrophin-1, DGS-I, nuclear factor NF90, HPIP1 and human HN1 homolog protein. Accordingly, the present invention discloses complexes of HPS protein and 14-3-3 protein, Hrs, atrophin-1, DGS-I, nuclear factor NF90, HPIP1 and human HN1 homolog protein, and derivatives, fragments and analogs thereof. Additionally, the present invention also discloses nucleic acids encoding the HPIP1 and human HN1 homolog protein, or derivatives, fragments and analogs thereof. Methods of screening the complexes or proteins for efficacy in treating and/or preventing certain diseases and disorders, particularly atopic diseases, autoimmune diseases, neurodegenerative disease, cancer, pigmentation disorders, platelet dysfunction and viral diseases, are also disclosed herein.
