Funkcija

uredi

Ovaj gen kodira treći otkriveni ljudski homolog membranskog proteina tipa zareznih proteina. Drosophila melanogaster. U rodu Drosophila, interakcija zareza sa njegovim ćelijski vezanim ligandima (delta, serata) uspostavlja međućelijski signalni put koji ima ključnu ulogu u razvoju neurona. Homolozi zareznog-liganda su također identificirani kod ljudi, ali treba precizno utvrditi interakcije između ovih liganada i homologa ljudskog zareznog proteina.

Patologija

uredi
 
Mikrografija CADASIL-a sa zarezom 3, imunoboja.

Mutacije u NOTCH3 identificirane su kao osnovni uzrok cerebralne autosomno dominantne arteriopatije, sa subkortikalnim infarktom i leukoencefalopatijom (CADASIL).[6] Mutacije u NOTCH3 također su identificirane u porodicama s Alzheimerovom bolešću.[7] Odrasli nokaut-miševi Notch3 pokazuju nepotpuno sazrijevanje neurona u leđnom rogu kičmene moždine, što rezultira trajno povećanom nociceptivnom osjetljivošću.[8]

Mutacije u NOTCH3 povezane su sa sindromom lateralne meningokele.[9]

Farmaceutski cilj

uredi

Notch3 se istražuje kao meta za lijekove protiv raka, jer je prekomjerno izražen u nekoliko tipova karcinoma.[10] Rana klinička ispitivanja Pfizer-ovog PF-06650808, antitela protiv Notch3 povezanog sa citotoksičnim lijekom, pokazala su efikasnost protiv solidnih tumora.[11]
