MOESM2 of Modulation of chromatin structure by the FACT histone chaperone complex regulates HIV-1 integration

Additional file 2: Table S2. List of additionally selected proteins. Cellular extracts from HeLa P4 cells were incubated with streptavidin beads coupled to fraction enriched in active IN•viral DNA complexes as shown in Additional file 1: Figure S1. The elution of the interacting proteins was loaded on 12% SDS-PAGE gel stained with silver nitrate and the bands were excised from gel and submitted to electroelution. The selected proteins were identified by MS–MS. A list of proteins found only associated to IN•viral DNA complexes but not to control DNA alone and linked to chromatin or transcription is provided here in addition to the factors reported in Table 1.
