Identification of hSSB1-associating proteins with a range of biological functions. The gel-embedded, coomassie blue-stained proteins in Fig. 1d were divided into eight 1 mM gel slices, digested with trypsin and extracted. Peptides were separated and detected using an Agilent HPLC CHIP QTOF 6530 system. The mass spectrum data was extracted and searched against the Swiss Prot Human database. Proteins for which corresponding peptides were identified, as well as the number of unique detected peptides, are given in Additional file 1. Proteins were manually sorted based on their predominant known biological process as given by UniProt (http://www.uniprot.org). Proteins identified from the hSSB1:IP sample are summarised as the number of unique proteins identified for each biological process
