Octopamine 60-70 Tyrosine decarboxylase 2 Drosophila melanogaster 141-146 15691831-5 2005 Flies with a mutation in dTdc2 lack neural tyramine and octopamine and are female sterile due to egg retention. Octopamine 56-66 Tyrosine decarboxylase 2 Drosophila melanogaster 25-30 15691831-9 2005 The egg retention phenotype of the dTdc2 mutant and the phenotypes associated with ectopic dTdc expression contribute to a model in which octopamine and tyramine have distinct and separable neural activities. Octopamine 138-148 Tyrosine decarboxylase 2 Drosophila melanogaster 35-40
