Abstract:
The assembly of hnRNP-like particles was studied by in vitro reconstitution, UV-crosslinking and CsCl-equilibrium centrifugation. Using total nuclear protein and RNA extracts from HeLa cells for RNP reconstitution, RNP particles sedimenting with the same buoyant density of p = 1.4 g/cm3 as 'native' 40 S core hnRNPs were obtained. Under the stringent reconstitution conditions used, hnRNP complexes containing only the Cl-core hnRNP protein could be identified.
