Historically, molecular bioscience has examined the function of individual molecules, an approach that may not predict the consequences of biological interactions [1]. The function of living organisms, however, cannot be resolved satisfactorily by examining molecules alone, not even if every molecule is usually analyzed individually in this way [2]. Indeed, proteins seldom carry out their function in isolation but rather operate through interactions with other biomolecules. Computational analysis and experimental verification of the complex networks created by individual proteinprotein interactions (PPIs) is one of the major challenges of the post-genomic era [3] and is essential if there is to be an understanding of the collective function of these activities. Many technologies, such as microarrays, two-dimensional SDS-PAGE, two-hybrid assays, co-immunoprecipitation and the chIPchip approach, have been used to study global changes and molecular interactions. The development of these high throughput techniques, together with the availability of large biological datasets, are the tools by which cellular functions can be analysed at a systems level. Tentative steps are now being taken to use this approach to study human disease [4] and to develop new therapeutic interventions [5,6]. Cellcell adhesion is involved in all aspects of tissue behaviour in multi-cellular organisms, from tissue morphogenesis (regulation of cell shape, apoptosis, cell movement and the development of complex structures) to ageing and disease [7]. Organised rearrangements of cellcell contacts in epithelial cells, for example, are invariably associated with spatio-temporal changes in the expression of cadherins, the main transmembrane proteins of desmosomes and adherens junctions [8]. Desmosomes are the principal intercellular junctions of stratified epithelia and play a central role in epithelial tissue homeostasis [9]. The desmosome consists of transmembrane adhesion molecules, including the cadherins [desmogleins (Dsg), desmocollins] and intracellular plaque proteins belonging to the families of plakins (desmoplakin, periplakin, envoplakin) and Armadillo proteins [plakoglobin and plakophilins (Pkps)]. Because desmosomes also link intracellularly to keratin intermediate filaments (KIF) in the cytoskeleton, termed the desmosome/intermediate filament complex (DIFC), an adhesive bond is established that confers mechanical stability to tissues [10]. Gene targeting has been employed to analyse the hierarchical function of desmosomal components, but by contrast to studies of adherens junctions, only a small number of genes (desmocollin 1, Dsg2, Dsg3, plakoglobin, pkp2, desmoplakin) have been ablated in mice [11]. However, the crucial role of the desmosome in maintaining epidermal integrity is widely demonstrated by the large number of diseases, be they genetic, immunological or infectious in origin, that occur when the function of one or more of desmosomal constituents is impaired [9,12]. Knowledge of the desmosome has evolved from the notion of a static, punctuate, adhesive barrier structure to one of a multi-component, multifunctional complex involved in the regulation of numerous and diverse aspects of keratinocyte physiology and disease [13]. An insight into the mechanisms that regulate the dynamics of keratinocyte adhesion, therefore, requires not only an understanding of desmosomal structure and function but also an understanding of how the desmosome responds to perturbations and the regulation of component parts. These perturbations can be either genetic (i.e. internal), resulting from one or more mutations or altered expression of desmosomal genes, or environmental (i.e. external), consequent to the processing of specific desmocadherins during infection or to the blocking of molecules such as Dsg in mucocutaneous autoimmune diseases (Electronic Supplementary Material, ESM, Fig. S1). Autoantibodies targeting keratinocyte adhesion molecules, for example, trigger massive changes in the desmosomal network leading to cellcell detachment, as is known to occur in Pemphigus Vulgaris (PV) [14]. In this disease, autoantibodies cause desmosomal remodelling, a process where PV IgG binds to Dsg1 and/or Dsg3, together with regulatory pathways triggered by non-Dsg3 antibodies, to induce molecular changes in desmosome composition and phosphorylation that lead to a failure of intercellular adhesion and cell detachment [14,15]. Recent in silico studies have demonstrated the usefulness of a system level analysis to build a roadmap of cell adhesion proteins and signalling [16,17].

An understanding into the systems that regulate the dynamics of keratinocyte adhesion, consequently, requires not merely a knowledge of desmosomal framework and function but also a knowledge of the way the desmosome responds to perturbations as well as the rules of element parts.
