We present, here, a detailed and curated map of molecularinteractions taking place in the regulation of the cell cycle bythe retinoblastoma protein (RB/RB1). Deregulations and/ormutations in this pathway are observed in most humancancers. The map was created using Systems BiologyGraphical Notation language with the help of CellDesigner3.5 software and converted into BioPAX 2.0 pathwaydescription format. In the current state the map contains 78proteins, 176 genes, 99 protein complexes, 208 distinctchemical species and 165 chemical reactions. Overall, themap recapitulates biological facts from approximately 350publications annotated in the diagram. The network containsmore details about RB/E2F interaction network than existinglarge-scale pathway databases. Structural analysis of theinteraction network revealed a modular organization of thenetwork, which was used to elaborate a more summarized,higher-level representation of RB/E2F network. The simpli-fication of complex networks opens the road for creatingrealistic computational models of this regulatory pathway.Molecular Systems Biology 4 March 2008; doi:10.1038/msb.2008.7Subject Categories: metabolic and regulatory networks; cell cycleKeywords: cell-cycle regulation; E2F; RB pathway; RB1; systems-biology standards

Introduction
The cell cycle is the succession of four phases called G1, S, G2andM. In dividing cells, DNA replication (S phase) andmitosis
(M phase) alternate (Alberts et al, 1994), and are separated bytwo gap phases, G1 and G2 phases. In quiescent cells, the cellsare considered to be in G0 phase. When they receive externalsignals, such as growth factors, a series of activations push thecell from a G0 to a G1 state and enters the cell cycle. The wholeprocess of cell division is mainly orchestrated by complexescomposed of two subunits, a kinase and a cyclin partner. Thesecomplexes phosphorylate a certain number of proteins, eitheractivating or inhibiting them. Among them, the retinoblasto-ma tumour suppressor protein RB (RB1) is a key regulator incell-cycle entry (transition G1/S). It sequesters a family oftranscription factors, the E2Fs, responsible for the transcrip-tion of many genes involved in cell-cycle regulation, DNAreplication and other functions like the activation of theapoptotic pathway (Muller et al, 2001). RB functions as a brakein the cell cycle, which is releasedwhen external signals triggerS-phase entry. The main targets of the external signals are theG1 cyclin/CDK complexes. Once active, the complexes, amongthem CycD1/CDK4,6, act as starters of the cell cycle (Novaket al, 2007) and phosphorylate RB, which then releases E2F(DeGregori, 2004).RB is a member of a family of proteins called the pocket
proteins (Knudsen and Wang, 1997). These proteins RB, p107and p130, share sequence similarities, especially in the ‘pocketdomain’ (Stevaux and Dyson, 2002), which is responsible fortheir repressor function. RB protein contains domains wherethe binding sites for co-repressors (E2F proteins and viraloncoproteins) are situated. These sites are subjected to mostmutations.RB is a tumour suppressor gene. Because of its implication in
so many, if not all, cancers (Sherr and McCormick, 2002), thestudy of RB regulation requires a special attention.More specifically, the RB/E2F pathway is commonly
deregulated in cancer through genetic or epigenetic mechan-isms, resulting in E2F activation. Several common oncogenes(involved in many cancer types) are the activators of thepathway, whereas several common tumour suppressor genesare inhibitors of the pathway. For example, cyclin D1 (CCND1),E2F3 and the two cyclin-dependent kinases CDK4 and CDK6can be activated by translocation, amplification or mutation,whereas RB (RB1) and the cyclin-dependent kinase inhibitorsp16INK4a (CNKN2A) and p15INK4b (CDKN2B) can beinactivated by point mutation, homozygous deletion or DNAmethylation. In addition, RB can be inactivated by severaloncogenic viral proteins including E7 from human papilloma-virus, which is responsible for more than 90% of cervicalcarcinomas (Munger et al, 2001). Tumour suppressor geneinactivation is found not only in sporadic tumours but also intumour-prone families. Germline mutations of RB1 results inretinoblastoma with a high penetrance early in youngindividuals and late in life in sarcomas and lung and bladdercarcinomas (Knudson, 1971; Nevins, 2001; Giacinti andGiordano, 2006). Germinal mutations of p16INK4a results in

are connected by ‘activation’ and ‘inhibition’ relations. Theinformation about these relations is derived from the detaileddiagram. For example, in the detailed map, E2F1 is phos-
phorylated by CycA2/CDK2 and is subsequently recognizedfor degradation, which is translated in the modular map byCycA2/CDK2 module inhibiting E2F1-3 module.
Figure 2 The textbook pathway of RB has been expanded by integrating data from the literature. The E2F transcription factors (represented here by single proteins inthe nuclear compartment) are connected by activation and inhibition arrows to their gene targets. (A) Map of target genes of E2F transcription factors. Each E2Fassociates with different cofactors to activate or inhibit the transcription of many genes; pointed arrows mean activation and flat arrows mean inhibitions (B) Map ofprotein–protein interaction network. Each icon on the diagram represents distinct chemical species. See Kitano and co-workers’ description of CellDesigner’s standardnotation (Kitano et al, 2005) for a detailed meaning of shapes. When the information is available (from Atlas Oncology web-page: www.atlasgeneticsoncology.org/),tumour suppressor genes and the corresponding proteins are coloured in blue and oncogenes in red, the other proteins are in green.
