A multifaceted strategy to improve recombinant expression and structural characterisation of a Trypanosoma invariant surface protein

View Original View Raw

Summary

This article discusses a multifaceted strategy to improve the expression and characterization of a Trypanosoma invariant surface protein (Tisp). The authors suggest using native mass spectrometry for direct characterization of proteins that have been overproduced. This strategy is expected to lead to improved understanding of Tisp structure, and potentially aid in the design of targeted antitrypanosomal drugs.

Technical terms

Recombinant Expression: Recombinant expression is a process in which a gene of interest is inserted into a host organism, such as a bacteria or yeast, and the gene is expressed, or translated into a protein.
Native Mass Spectrometry: Native mass spectrometry is a technique used to analyze proteins in their native state, without the need for denaturing or unfolding them. It is used to identify and quantify proteins, as well as to determine their structure and interactions.
Trypanosoma invariant surface protein: Trypanosoma invariant surface protein (TISP) is a protein found on the surface of the parasite Trypanosoma, which is responsible for causing sleeping sickness. It is involved in the attachment of the parasite to the host cell and is a potential target for drug development.
