Mice homozygous for targeted mutations that inactivate the gene are viable and fertile with reduced exploratory activity and displaying depressive rather than stimulatory response to caffeine. Mutants test more anxious, were more aggressive towards intruders, and slower to respond to pain stimuli. Blood pressure and heart rate are increased, as well as platelet aggregation rate.
