PROBLEM TO BE SOLVED: To provide a novel protein which is expressed uniquely during incubation infection of herpes virus, a gene for coding the protein, and the use thereof.SOLUTION: Protein formed of an amino acid sequence indicated on an array number 1 and protein which is coded to a nucleic acid having a base sequence indicated on an array number 2 as an opening reading area, are factors related to incubation infection of herpes virus. To almost 50% of mental disordered patients, an antibody to the factors is detected, but to healthy people, the antibody is hardly detected. A mouse to which SITH-1 is introduced, has indicated mental disorder such as manic depressive illness or depression. Therefore, based on the fact, a method for objectively determining mental disorder and a mental disorder model animal can be provided.
