Summary

Automatic Translation

Protein interaksjoner er i hjertet av en celle funksjon. Kalorimetriske og spektroskopiske teknikker blir ofte brukt for å karakterisere dem. Her beskriver vi fluorescens anisotropi som et verktøy for å studere samspillet mellom protein mutert i Shwachman-Diamond syndrom (SBDS) og Forlengelse faktor-lignende en GTPase (EFL1).
