Octopamine 0-10 Tyrosine decarboxylase Caenorhabditis elegans 33-55 30065850-9 2018 Mutant analyses showed that tbh-1 mutants lacking only octopamine had normal calcium responses, whereas tdc-1 mutants lacking both tyramine and octopamine did not exhibit the calcium decrease in RME. Octopamine 144-154 Tyrosine decarboxylase Caenorhabditis elegans 104-109
