The present invention provides methods to characterize the structure, stability, and intersubunit interfaces between the matrix, capsid, and nucleocapsid domains of the Gag polyprotein during HIV capsid assembly and maturation. A method of screening for compounds that promote or inhibit viral assembly and maturation is disclosed. A novel mass spectrometry based approach to measure hydrogen/deuterium exchange profiles is also disclosed. Quantitative data resulted from these studies may lead to well defined capsid assembly assays that can be adapted for rapid antiviral drug screening.

La présente invention se rapporte à des méthodes visant à caractériser la structure, la stabilité et les interfaces entre sous-unités des domaines de la matrice, de la capside et de la capside nucléique de la polyprotéine Gag au cours de l'assemblage de la capside du VIH et de sa maturation. L'invention se rapporte à un procédé de sélection de composés qui favorisent ou inhibent l'assemblage et la maturation du virus. L'invention se rapporte également à une nouvelle approche, fondée sur la spectrométrie de masse, de mesure des profils d'échange hydrogène/deutérium. Les données quantitatives résultant de ces études peuvent conduire à des méthodes bien définies d'assemblage de la capside qui peuvent être adaptées pour permettre une sélection rapide de médicaments antiviraux.
