Knockout mutant mouse for DARPP-32 and use thereof

摘要

A knockout mouse containing a non-functional allele for the gene that naturally encodes and expresses functional DARPP-32 is disclosed. This mouse contains two non-functional alleles for the gene that naturally encodes and expresses functional DARPP-32, and therefore is unable to express functional DARPP-32. This mouse finds utility as a screening model for potential therapeutic agents useful in the treatment of schizophrenia, Parkinson's disease, and the treatment of addictions, especially those involving drugs of abuse.
