N normal phenotype
muscle
impaired muscle contractility ( J:114415 )
• peak tetanic force produced by extensor digitorum longus (EDL) muscle at supramaximal stimulation is ~240 mN/sq. mm compared to 297 mN/sq. mm in wild-type
• EDL muscle produces similar twitch force to wild-type muscle
• contractility of mutant muscle is increased with ouabain inhibition of Atp1a2
• constant for fatigue is similar to wild-type

N normal phenotype
behavior/neurological
enhanced behavioral response to addictive substance ( J:117414 )
• increase in peak activity elicited by methamphetamine and prolonged habituation time
abnormal locomotor activation ( J:117414 )
• increased swimming speed during hidden platform training in a Morris water maze; however, latency to find the platform is not significantly different from wild-type

homeostasis/metabolism
increased circulating corticosterone level ( J:117414 )
• increase in basal and post methamphetamine challenge serum levels
• however, levels of norepinephrine, dopamine, serotonin, and their metabolites are all similar to wild-type mice
