PCDH11X
X-vezani protokaderin 11, poznat i kao PCDH11X, jest protein koji je kod ljudi kodiran genom PCDH11X.[5][6]
Funkcija
urediOvaj gen pripada porodici protokaderinskih gena poporodici superporodice kaderina. Kodirani protein sastoji se od vanćelijskog domena sa sedam ponavljanja kaderina, transmembranske domene i citoplazmatskog repa koji se razlikuje od onog kod klasičnih kaderina. Gen se nalazi u glavnom X/ Y bloku homologije i njegov Y homolog (PCDH11Y), uprkos divergenciji koja dovodi do promjena u kodirajućem području, najuži je član porodice kaderina. Smatra se da ovaj protein igra osnovnu ulogu u prepoznavanju ćelija-ćelija neophodnom za segmentni razvoj i funkciju centralnog nervnog sistema. Transkripti koji proizlaze iz alternativne prerade kodiraju izoforme s promjenjivim citoplazmatskim domenima.[5]
Klinički značaj
urediU svegenomskoj studiji povezanosti, gen PCDH11X nađen je kao faktor rizika u kasnom nastanku Alzheimerove bolesti,[7] ali druge studije o različitim populacijama [8][9][10][11] nisu mogle potvrditi početnu povezanost. Klinički značaj ovog gena nije jasan i može imati različite uloge u različitim, populacijski specifičnim kontekstima.
