background: protein-protein interactions do not provide any direct information re­garding the domains within the proteins that mediate the interactions. the majority of proteins are multi domain proteins and the interaction between them is often defined by the pairs of their domains. most of the former studies focus only on interacting do­main pairs. however they do not consider the interaction...

The 26-subunit, 1.2 MDa human Mediator complex is essential for expression of perhaps all protein-coding genes. Activator binding triggers major structural shifts within Mediator, suggesting a straightforward means to spatially and temporally regulate Mediator activity. By using mass spectrometry (MudPIT) and other techniques, we have compared the subunit composition of Mediator in three differ...
