Binding proteins belong to the following group: A natural ligand or a genetically modified ligand, a recombinant soluble domain of a natural receptor or a modified version of it, a peptide-ligand, an antibody molecule and derivatives thereof or antibody-like molecules like ankyrin repeat molecules or derivatives thereof.

Diacylglycerol (DAG) plays a central role in both the synthesis of complex lipids and in intracellular signaling; diacylglycerol kinase (DGK) catalyzes the phosphorylation of DAG, which yields phosphatidic acid. A family of DGKs has been identified in multicellular organisms over the past few years, but the physiological function(s) of this diversity is not clear. One clue has come from the Drosophila DGK2, rdgA, since mutations in this gene cause retinal degeneration. The present invention relates to a novel DGK, designated DGKι, which was isolated from human retina and brain libraries. DGKι contains two cysteine-rich repeats, a region similar to the phosphorylation site domain of MARCKS, a conserved catalytic domain, and four ankyrin repeats at its C-terminus. By primary structure, DGKι is most similar to human DGKζ and Drosophila rdgA. A>12 kb mRNA for DGKι was detected only in brain and retina among the tissues examined. In cells transfected with the DGKι cDNA, an approximately 130 kDa protein was detected by immunoassay, and activity assays demonstrated that it encodes a functional DAG kinase. The protein was found to be in both the cytoplasm and nucleus, with this localization controlled by PKC isoforms alpha and gamma. The gene encoding DGKι was localized to human chromosome 7q32.3-33, which is known to be a locus for an inherited form of retinitis pigmentosa. These results have defined a novel isoform of DAG kinase, which may have important cellular functions in the retina and brain.

New designed ankyrin repeat proteins with binding specificity for HGF are described, as well as nucleic acids encoding such HGF binding proteins, pharmaceutical compositions comprising such proteins and the use of such proteins in the treatment of diseases.

The invention discloses novel application of an ankyrin repeat domain-containing 13A gene and/or a protein encoded by the same. An acute myeloid leukemia (AML) diagnosis and prognosis related molecular marker is screened to obtain an ankyrin repeat domain-containing 13A gene(ANKRD13A) closely related to AML patient prognosis; the high expression of ANKRD13A in the body of an AML patient warns poorprognosis; the ANKRD13A can be used as an independent factor for influencing the prognosis of the AML patient; the ANKRD13A is related to the FAB typing and the cytogenetics risk stratification of the AML patient; and the ANKRD13A may participate in the disease progression of AML through a variety of pathways. The ANKRD13A can be used for preparing a therapeutic drug or a prognosis detection reagent for the acute myeloid leukemia.
