Epidermal Growth Factor domain-specific O-linked N-acetylglucosamine Transferase (Eogt) is a specialized glycosyltransferase that catalyzes the addition of O-linked N-acetylglucosamine (O-GlcNAc) modifications to proteins containing epidermal growth factor (EGF)-like domains. Discovered in 2011. Eogt differs from the broader O-GlcNAc transferase (OGT) by its substrate specificity, targeting extracellular EGF-repeat proteins rather than intracellular nucleocytoplasmic proteins. This post-translational modification, termed EGF-O-GlcNAcylation, plays critical roles in regulating protein folding, trafficking, and signaling, particularly in the Notch signaling pathway—a key regulator of cell differentiation and development.
Recombinant Eogt proteins are engineered to study its enzymatic activity, substrate interactions, and structural mechanisms. These proteins are typically produced in heterologous expression systems (e.g., bacterial or mammalian cells) using gene cloning techniques. Purified recombinant Eogt enables in vitro studies to map O-GlcNAc sites, characterize enzyme kinetics, and explore its interplay with other glycosyltransferases. Research highlights its importance in development, as Eogt knockout models display embryonic lethality in mice and developmental defects resembling Adams-Oliver syndrome in humans. Additionally, aberrant Eogt activity is implicated in cancer metastasis and cardiovascular diseases, making it a potential therapeutic target.
The development of recombinant Eogt has advanced tools for probing O-GlcNAc biology, offering insights into extracellular glycosylation’s role in cellular communication and disease. Further studies aim to unravel its tissue-specific functions and therapeutic applications in glycosylation-related disorders.
