Proteomics tsom rau cov lus piav qhia zoo ntawm kev tswj hwm gene, kev txiav txim siab ntau ntau ntawm cov protein ntau ntawm cov noob qhia, kev txheeb xyuas qhov tshwm sim ntawm cov kab mob thiab tshuaj nyob rau lub neej muaj txheej txheem, thiab piav qhia txog kev ua kom muaj kev cuam tshuam ntawm cov txheej txheem ntawm noob qhia kev cai. Raws li kev tshawb fawb, cov kev tshawb fawb proteomics tsis yog los ntawm xoom Pib, nws yog qhov txuas ntxiv ntawm cov protein (peptide) cov ntaub ntawv thiab cov khoom lag luam daim phiaj qhia ntawv tshuab uas tau siv rau ntau tshaj 20 xyoo. Peptide daim qhia chaw cia siab rau ob txoj kev sib luag ntawm cov xim electrophoresis (2-DE) thiab tshawb xyuas cov duab txuas ntxiv; thiab cov gene Cov ntaub ntawv khoom lag luam nyob ntawm ntau cov kev txheeb xyuas tom qab sib cais, xws li cov huab hwm coj loj, cov tshuaj amino acid sib xyaw, thiab lwm yam.
Vim tias muaj cov kuj sib txawv thiab cov RNA editing, ntau tus noob tuaj yeem hais tawm ntau hom protein sib txawv. Yog li no, qhov tsis yooj yim ntawm cov tiv thaiv kab ke muaj ntau dua qhov nyuaj ntawm cov genome.
Yog tias tag nrho cov keeb xaj ntawm hom tau txiav txim siab, nws tsis txhais tau tias cov khoom cog ntawm cov hom ntawd kuj tau txiav tawm. Cov kev soj ntsuam tshwj xeeb ntawm cov khoom muaj protein ntawm cov noob yuav tsum txiav txim siab los ntawm cov kev hloov kho kom zoo thiab kev tswj hwm theem, cov theem hloov thiab qib txhais lus.
