ProteomicsIdentification and analysis of histone lysine 2-hydroxyisobutyrylation in Arabidopsis
Lysine 2-hydroxyisobutyrylation (Khib) is a novel type of histone acylation in eukaryotes, but its prevalence and genomic function in higher plants remain unclear. Using mass spectrometry, we identified histone lysine 2-hydroxyisobutyrylation in Arabidopsis

ProteomicsQuantitative Proteomics Reveals the role of Lysine 2-hydroxyisobutyrylation Pathway mediated by Tip60
Lysine 2-hydroxyisobutyrylation (Khib) is an evolutionary conserved and widespread protein posttranslational modification (PTM) that has diverse cellular functions. Recently, it has been demonstrated that Khib can be regulated by p300 and Tip60. Although the specific Khib substrates mediated by p300...

Giardia lamblia (G. lamblia) disease is a zoonosis with a-infection rate affecting the general population of the world. Despite the constant possibility of damage due to their own metabolism, G. lamblia have survived and evolved to adapt to various environments. However, research on energy-metabolis...
