Description | ThetranscriptionfactorAP-1(activatorprotein-1)isinvolvedincellularproliferation,transformationanddeath.AP-1andnuclearfactorB(NF-kB)canbespecificallytargetedtopreventcancerinductioninmousemodels.AP-1canbeproducedby18differentdimericcombinationsofproteinsfromtheJun(c-Jun,JunBandJunD)andFos(c-Fos,FosB,Fra-1andFra-2)families,includingJunhomodimersandJun–Fosheterodimers(1–4).TheJunandFosproteinscontainabasic-regionleucinezipper(bZIP)domain,andarecapableofbindingtootherbZIPproteinsincludingthosefromtheATF,MAF,CNCandC/EBP(CCAAT/enhancer-bindingprotein)subfamilies(5])Jun–JunandJun–Fosdimersbindwithhighestaffinitytothe12-O-tetradecanoylphorbol-13-acetate(TPA)responseelement(TRE)[TGA(C/G)TCA](6),althoughmanyother`AP-1-likesites`havebeenreported.Bindingtoanyofthesesitescanbetissue-specific,oraffectedbyneighboringsequences,anddependentuponinteractionswithothertranscriptionfactorsorcofactors.JunandFosproteinscanalsodimerizewithotherbZIPproteins,allowingthemtotargetotherDNAbindingsites,suchasthecAMPresponseelement(CRE),theantioxidantresponseelements(ARE),andhalf-sitescomposedofhalfofaTREsiteandhalfofaMAF-orCNC-bindingsite.Inaddition,AP-1proteinscaninteractwithotherproteins,includingthep65subunitofNF-kB,CBP(CRE-binding-protein-bindingprotein)(p300),SMAD-3and-4,andtheretinoblastomaprotein(see5foramorecompletelist),furtherincreasingthecombinatorialpotentialofJunandFosproteins.AP-1regulatesavarietyofcellularprocesses,includingproliferation,differentiationandapoptosis,andcontributestobothbasalandstimulus-activatedgeneexpression.Itisactivatedbygrowthfactors,hormones,stress,cytokines,ROSandultravioletrADIationActivationoccursbothtranscriptionallyandpost-translationally,andissignaledpredominantlythroughthemitogen-activatedproteinkinase(MAPK)cascade(7).ThecombinatorialdiversityofAP-1proteinsandotherinteractingfactorsappearstoinfluencehowspecificcelltypesrespondtoastimulus.Thegrowth-promotingactivityofc-Junismediatedbyrepressionoftumorsuppressors,aswellasup-regulationofpositivecellcycleregulators.Mostly,c-Junisapositiveregulatorofcellproliferation,whereasJunBhastheconverseeffect(8). |
