One step N-terminal tagging of endogenous proteins for therapeutic delivery, diagnostics, and in vivo imaging

N-Terminal protein modification using adenosine substrates and aminoacyl transferase Problem: The conjugation of synthetic molecules to the termini of proteins with minimal effects on protein folding and function is an active area of biochemical research. Previous N-terminal protein modification methods suffer from side reaction products, incomplete...

Non-perturbative, site-specific labeling of α-synuclein for studying amyloid disease and screening therapeutics

Fluorescently labeled α-synuclein to examine destabilization of synuclein fibrils by small molecules and therapeutics for neurodegenerative diseases Problem: Misfolding of the neuronal protein α-synuclein triggers oligomerization and the formation of amyloid fibrils that are the pathological hallmarks of Parkinson’s disease. The...
