Table 1: List of only the known androgen-receptor-interacting proteins and coregulators (http://androgendb.mcgill.ca) identified after mass spec analysis of all gel fractions (Figure 3(a)) from FLAG purifications of nuclear extracts from P17 cells grown under proliferating and nonproliferating conditions (see Section 2). (a) Listed are the interacting proteins that were unique for the proliferating cells (33 only), interacting proteins that were unique for the nonproliferating cells (37 only), and (b) interacting proteins common to both (common). The AR is highlighted. Given are the Uniprot accession numbers identified by the database Mascot search (Uniprot), the score achieved in the peptide summary report (score), the gel slice number (), and information whether the protein had been identified as a coactivator (CoA), corepressor (coR), or the effect has not been reported (—). Activating function has been allocated to GSN [13, 14], without distinguishing between the 2 isoforms [15].
