MEKK1(SERINE THREONINE KINASES)-INTERACTING FHA (FORKHEAD ASSOCIATED DOMAIN) PROTEIN 1 (MIF1)

摘要

The present invention relates to a novel protein of the MEKK signal transduction pathway, and the gene encoding it. The invention further relates to diagnostic and therapeutic uses of the protein or the gene, and to methods of screening for agonists or antagonists of the protein, particularly with respect to MEKK activity. In particular, the invention provides a gene encoding MIF1, the MIF1 protein, and antibodies that specifically bind MIF1. MIF1 and the MIF1 gene can be used in screening assays, particularly to identify agonists and antagonists of MIF1 interaction with MEKK, and thus modulators of the MEKK signal pathway. MIF1 gene (or cDNA) can also be delivered to cells, e.g., for in vitro screening or testing, or in vivo or ex vivo for gene therapy.
