Funkcija

[uredi | uredi izvor]

Notch 2 je član porodice notch. Članovi ove porodice transmembranskih proteina tipa 1 dijele strukturne karakteristike, uključujući vanćelijski domen koji se sastoji od višestrukih ponavljanja sličnih epidermnim faktorima rasta (EGF) i unutarćelijski domen koji se sastoji od više različitih tipova domena. Članovi porodice Notch imaju ulogu u raznim razvojnim procesima, kontrolišućirješenja o sudbini ćelije. Notch signalna mreža je evolucijski konzervirani međućelijski signalni put koji regulira interakcije između fizički susjednih ćelija. Kod Drosophila, interakcija Notch-a sa svojim ćelijskim ligandima (delta, serat) uspostavlja međućelijski signalni put koji ima ključnu ulogu u razvoju. Homolozi notch-liganda su također identifikovani kod ljudi, ali precizne interakcije između ovih liganada i ljudsjih homologa ostaju da se utvrde. Ovaj protein se cijepa u trans-Golgi mreži i edksprimira na površini ćelije kao heterodimer. Ovaj protein funkcionira kao receptor za ligande vezane za membranu i može imati ulogu u razvoju vaskularne mreže, bubrega i jetre.[9]

Pokazalo se da su mutacije unutar posljednjeg kodirajućeg egzona Notch2 koje uklanjaju PEST domen i izbjegavaju nonsens posredovani raspad iRNK glavni uzrok Hajdu–Cheneyevog sindroma.[10][11][12]
