Glycosylation of Tetraspanin Tspan-1 at Four Distinct Sites Promotes Its Transition Through the Endoplasmic Reticulum
We showed that Tspan-1, a tetraspanin overexpressed in many human cancers, harbours oligosaccharides at all four potential N-glycosylation sites. Its most abundant form contained only mannose-rich sugar chains but two distinct glycosylation sites could also contain complex carbohydrates. Glycosylation seemed to be required for correct folding and subsequent transition through the endoplasmic reticulum.

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.
