Title:MolecularDynamicsStudyoftheStructureandFunctionofGlycogenSynthaseKinase-3β

Background:Glycogensynthasekinase-3β(GSK-3β)isaserine/threonineproteinkinasethatisinvolvedinawiderangeofcellularprocesses.Itisakeyenzymeinglycogensynthasemetabolism,insulinsignaling,andcellcycleregulation.DysregulationofGSK-3βhasbeenimplicatedinseveraldiseases,includingtype2diabetes,Alzheimersdisease,andcancer.Therefore,understandingthestructureandfunctionofGSK-3βisofsignificantimportanceindevelopingtargetedtherapiesforthesediseases.

Objective:TheaimofthisstudyistoinvestigatethedynamicpropertiesoftheGSK-3βproteinusingmoleculardynamicssimulations.Specifically,wewillfocusonunderstandingthestructuralchangesandfunctionalimplicationsofGSK-3βphosphorylationbyexaminingitsinteractionswithsubstrates,inhibitors,andotherregulatoryproteins.

Methods:WewillperformmoleculardynamicssimulationsonthecrystalstructuresofGSK-3βinitsactiveandinactivestates.Thesimulationswillbecarriedoutusingdifferentforcefieldsandconditionstoexplorethepotentialenergylandscapeandconformationalspaceoftheprotein.

ExpectedResults:ThemoleculardynamicssimulationswillprovidevaluableinsightsintothestructureandfunctionofGSK-3β.Specifically,weexpecttoidentifythekeyresiduesinvolvedinsubstratebindingandphosphorylation,aswellastheconformationalchangesassociatedwithGSK-3βactivationandinhibition.TheseresultswillenhanceourunderstandingofthemechanismofactionofGSK-3βandfacilitatethedevelopmentofnoveltherapeuticstrategiestargetingGSK-3β.

Conclusion:ThisstudywillcontributetoabetterunderstandingofthestructureandfunctionofGSK-3β,akeyenzymeinseveralcellularprocesses.Theresultsofthisstudymayhavesignificantimplicationsforthedevelopmentofeffectivetherapie
