Gene expression is crucial for cellular functions and homeostasis, with histone modifications playing a role in regulating gene expression. Recent studies have shown how tissue transglutaminase 2 mediated histone glutamine modifications can regulate gene expression, opening new avenues in the field of epigenetics and neuroepigenetics. The research aims to identify enzymes responsible for reversible reactions of histone de-dopaminylation and de-serotonylation.
Gene expression is the key to cellular functions and homeostasis. Histone modifications regulate chromatin dynamics and gene expression. Neuronal cell functions largely depend on fluxes of neurotransmitters for activation of chromatin and gene expression. New studies by Lepack et al. and Farrelly et al. recently demonstrated how tissue transglutaminase 2 (TGM2) mediated histone glutamine modifications, either dopaminylation in the dopaminergic reward pathway or serotonylation in the context of cellular differentiation and signaling regulate gene expression and decipher striking differences from their known functions. This opens new avenues of research in the field of epigenetics in general and neuroepigenetics as special; and to find out the enzymes responsible for the reversible reaction of histone de-dopaminylation and de-serotonylation.
