<p>A novel brain-specific adapter molecule, its gene, an antibody to it, and a method of utilizing the antibody are provided. This invention screened a normalized cDNA library using mRNA derived from the human cerebrum, isolated a gene encoding a novel factor, FC99 protein, involved in the signaling pathways in neurons of the brain, and clarified its base sequence as well as a protein encoded by the gene. The invention also isolated from a rat brain-derived cDNA library a gene encoding rat FC99 protein, and clarified its base sequence as well as a protein encoded by the gene. The invention further produced an antibody to the protein, and measured tyrosine kinase activity in a cell by use of the antibody.</p> |
