Comment on "Tequila, a Neurotrypsin Ortholog, Regulates Long-Term Memory Formation in Drosophila"
Peter Sonderegger1* and
Laszlo Patthy2
Didelot
et al. (Reports, 11 August 2006, p. 851) claimed that
Drosophila Tequila (Teq) and human neurotrypsin are orthologs
and concluded that deficient long-term memory after Teq inactivation
indicates that neurotrypsin plays its essential role for human
cognitive functions through a similar mechanism. Our analyses
suggest that Teq and neurotrypsin are not orthologous, leading
us to question their equivalent roles in higher brain function.
