Glukoza fosfat izomeraza‎, takođe poznata kao GPI, je ljudski protein kodiran GPI genom.[1]

Funkcije[уреди]

Ovaj gen pripada GPI familiji čiji članovi kodiraju multifunkcionalne fosfoglukozne izomeraze koje učestvuje u energetskim putevima. Protein kodiran ovim genom je dimerni enzim koji katalizuje reverzibilne izomerizacije glukoze 6-fosfata i fruktoze 6-fosfata.

glukoza 6-fosfat <=> fruktoza 6-fosfat

GPI ima različite funkcije unutar i izvan ćelije. U citoplazmi, ovaj protein učestvuje u glikolizi i glukoneogenezi, dok van ćelije on funkcioniše kao neurotrofilni faktor za kičmene i senzorske neurone. Identičan protein izlučuju ćelije raka. Protein izlučen iz tih ćelija je poznat kao autokrini faktor motiliteta[2]. On stimuliše metastazu.[3] Defekti ovog gena mogu da prouzrokuju nonsferocitnu hemolitičku anemiju, i jaka enzimska deficijencija može biti asocirana sa hydrops fetalis, brzom neonatalnom smrću i neurološkim oštećenjima.[1]
