Newly known KCNQ polypeptides and their use in the diagnosis of mental disorders

摘要

The invention relates to the use of PP2A/Bgamma and to the use of a PP2A phosphatase comprising the PP2A/Bgamma subunit for screening for modulators thereof. The use of these modulators for treating mental disorders such as bipolar disorder, schizophrenia and depression, and drugs comprising these modulators are further disclosed. The invention also discloses biallelic markers located in the gene encoding PP2A/Bgamma and their use for diagnosing mental disorders.
