During analysis of the proteome in the cerebrospinal fluid (CSF) of the Caucasian form of moyamoya disease (MMD), a novel post-translational modification of human transthyretin was observed. Two-dimensional electrophoresis and subsequent peptide sequencing with ESI-MS/MS were performed to discover the γ-carboxylation of the Glu-42 (Gla- 42).

More about this publication?
  • Protein & Peptide Letters publishes short papers in all important aspects of protein and peptide research, including structural studies, recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design etc. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallisation, and preliminary structure determinations of biologically important proteins are acceptable. Purely theoretical papers are also acceptable provided they provide new insight into the principles of protein/peptide structure and function.
