Functional divergence in the role of N-linked glycosylation in smoothened signaling [PDF]
, 2015 The G protein-coupled receptor (GPCR) Smoothened (Smo) is the requisite signal transducer of the evolutionarily conserved Hedgehog (Hh) pathway. Although aspects of Smo signaling are conserved from Drosophila to vertebrates, significant differences have ...

Evaluating Mechanisms of IDH1 Regulation through Site-Specific Acetylation Mimics
Biomolecules, 2021 Isocitrate dehydrogenase (IDH1) catalyzes the reversible NADP+-dependent oxidation of isocitrate to α-ketoglutarate (αKG). IDH1 mutations, primarily R132H, drive > 80% of low-grade gliomas and secondary glioblastomas and facilitate the NADPH-dependent ...

Post-translational protein modifications in schizophrenia [PDF]
npj Schizophrenia, 2020 AbstractResearch investigating the pathophysiology of schizophrenia has not yet precisely defined the molecular phenotype of this disorder. Many studies have investigated cellular dysfunction by examining expression levels of molecular targets in postmortem patient brain; however, inconsistencies between transcript and protein measures in schizophrenia
