title: [The C1473G polymorphism in gene tph2 is the main factor mediating the genetically defined variability of tryptophan hydroxylase-2 activity in the mouse brain].
abstract: Brain neurotransmitter serotonin is involved in the regulation of many physiological functions and types of behavior. The key enzyme of serotonin synthesis in the brain is tryptophan hydroxylase-2 (TPH-2). An association of the C1473G polymorphism in gene tph2 causing the replacement of Pro447 by Arg447 in TPH-2 molecule with enzyme activity in the mouse brain of 10 inbred strains was found. Association of the polymorphism with the TPH-2 activity in the brain of F2 hybrids between strains C57BL/6 and CC57BR was shown. The results indicate that the C1473G polymorphism in gene tph2 is the main factor determining the genetic defined variability of enzyme activity in the mouse brain.
