AMP-deaminata 3 je enzim koji je kod ljudi kodiran genom AMPD3.[5][6]

Ovaj gen kodira člana porodice gena AMP-deaminaza. Kodirani protein je visoko regulirani enzim koji katalizira hidrolitsku deaminaciju adenozin-monofosfata u inozin-monofosfat, tačku grananja u adenilatnom katabolitskom putu. Ovaj gen kodira izoforme eritrocita (E), dok drugi članovi porodice kodiraju izoforme koje prevladavaju u mišićnim (M) i jetrenim (L) ćelijama. Mutacije u ovom genu dovode do klinički asimptomskog, autosomno recesivnog stanja, nedostatka AMP-deaminaze eritrocita. Opisane su i alternativno prerađenesu varijante transkripta koje kodiraju različite izoforme ovog gena.[6]

Aminokiselinska sekvenca[uredi | uredi izvor]

Dužina polipeptidnog lanca je 767 aminokiselina, a molekulska težina 88.812 Da.[7]

U proučavanju PNPO funkcije, korišteni su modelni organizmi. Uvjetna linija nokaut-miševa, zvana Pnpotm1a (KOMP) Wtsi,[12][13] generirana je kao dio programa Međunarosnog konzorcija za nokaut-miševe – visokopropusnog projekta mutageneze za generiranje i distribuciju životinjskih modela bolesti zainteresiranim naučnicima.[14][15][16]

Muške i ženske životinje prolazile su standardizirani fenotipski skrining, kako bi se utvrdili efekti delecije.[10][17] Od 24 izvedena testa ina mutantnim miševima, uočene su dvije značajne abnormalnosti.[10] Tokom gestacije, nije utvrđen homozigotni mutantni embrion, pa tako nijedan nije preživio do odvikavanja. Preostali testovi su izvedeni na mutiranim heterozigotnim odraslim miševima; opažene su četiri značajijne abnormalnosti kod ovih životinja.[10] Druga mišja linija, zvana Ampd3T689A, generirana je mutagenezom ENU.[18] Ovaj miš nosi mutaciju koja povećava funkciju AMPD3. Mutantne životinje imaju značajno kraći životni vijek crvenih krvnih ćelija, cikličku eritropoezu, splenomegaliju i otpornost na infekciju sa Plasmodium chabaudi .
