Annotation of Non-Synonymous Single Polymorphisms in Human Liver Proteome by Mass Spectrometry
Abstract:A novel strategy to annotate nsSNP-peptides in human liver proteome based on LC-ESI-MS/MS and peptide database search was proposed. Totally 115 nsSNP-peptides in human liver proteins were annotated using our method. Among them, 42 peptides were found to be amino acid mutation, 73 peptides were wild type, 5 peptides were interpreted with both mutation and wild type. The function of nsSNP-peptide was predicted using SIFT algorithm, and 2 nsSNPs were predicted to be damaged for protein function. The results here show that the strategy is very effective for annotation of nsSNP at peptide level.

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.
