In sum, we show that the majority of oxytocin neurons in the male and female mouse Lonafarnib coexpress Fto. This transcription co-activator up-regulates oxytocin mRNA levels. The relationship between Fto and oxytocin could thus be an important mechanism through which Fto exerts its effect on energy balance.

Protein tyrosine phosphatase; Trypanosoma cruzi; Chagas’ disease; Recombinant expression
Protein tyrosine phosphatases (PTPs) form a large family of proteins in eukaryotic genomes with a wide range of functions . Solution of the structures of several PTPs has established an enzymatic mechanism where a catalytic cysteine from the core catalytic motif (H/V)C(X)5R(S/T) (Supplementary Fig. S1) acts as a nucleophile to form a covalent thiophosphate intermediate with the substrate. This intermediate is additionally stabilized by a catalytic arginine and hydrolyzed with the help of a catalytic aspartate, which functions as a general acid/base  and .
