Funkcija

Rekombinacijski popravak oštećenja dvostrukog lanca DNK - neki ključni koraci. ATM (ATM) je protein-kinaza koju regrutuju i aktiviraju dvolančani prekidi DNK. Dvolančana oštećenja DNK također aktiviraju jezgarni kompleks Fanconijeve anemije (FANCA/B/C/E/F/G/L/M).^[6] Jezgarni kompleks FA monoubikvitinira i nizvodno cilja na FANCD2 i FANCI.^[7] ATM aktivira fosforilira) CHEK2 i FANCD2^[8] CHEK2 fosforilira BRCA1.^[9] Ubikinirani kompleksi FANCD2 djeluju sa BRCA1 i RAD51.^[10] Protein PALB2 djeluje kao čvorište,^[11] spajajući BRCA1, BRCA2 i RAD51 na mjestu prekida dvolančane DNK, a također se vezuje za RAD51C, člana RAD51 paralognog kompleksa RAD51B-RAD51C-RAD51D-XRCC2 (BCDX2). Kompleks BCDX2 odgovoran je za angažovanje RAD51 ili stabilizaciju na mjestima oštećenja.^[12] RAD51 ima glavnu ulogu u homolognoj rekombinacijialnoj popravci DNK tokom popravljanja dvostrukog lanca. U ovom procesu, odvija se razmjena lanaca DNK, zavisna od ATP-a u kojoj jedan lanac napada lančiće uparene bazama homolognih molekula DNK. RAD51 je uključen u potragu za homologijom i fazama uparivanja lanaca u procesu.

Klinički fenotip mutacijskih defekata u svim komplementarnim grupama Fanconijeve anemije (FA) je sličan. Ovaj fenotip karakterizira progresivno zatajenje koštane srži, sklonost kanceru i tipski urođeni defekti.^[13] Glavni ćelijski fenotip je preosjetljivost na oštećenje DNK, posebno unakrsne veze DNK među lancima.^[14] FA proteini interaguju putem višeproteinskog puta. Međulančane umrežene veze DNK su veoma štetna oštećenja koja se popravljaju homolognom rekombinacijom, uključujući koordinaciju FA proteina i "gena za osjetljivost na rak dojke 1 (BRCA1)".

Put popravka DNK kod Fanconijeve anemije (FA) je neophodan za prepoznavanje i popravku umreženih međulančanih DNK (ICL). Kritični korak na putu je monoubikvitinacija FANCD2, pomoću RING E3-ligaza FANCL. FANCL se sastoji od tri domena, RING domena koji je u interakciji sa E2 konjugirajućim enzimima, centralnog domena potrebnog za interakciju supstrata i N-termin alnog E2-likog nabora domena (ELF) koji komunicira sa FANCB.^[15] ELF domen FANCL-a je također potreban da posreduje u nekovalentnoj interakciji između FANCL i ubikvitina. ELF domen je potrebna za podsgticanje efikasne monoubikvitinacije FANCD2 izazvane oštećenjem DNK u ćelijama kičmenjaka, što ukazuje na važnu funkciju FANCB i vezivanje ubikvitina od strane FANCL in vivo.^[16]

Jedarni kompleks koji sadrži FANCL (kao i FANCA, FANCB, FANCC, FANCE, FANCF, FANCG i FANCM) je neophodna za aktivaciju FANCD2 proteina na monoubikvitiniranu izoformu.^[6] U normalnim, nemutantnim, ćelijama FANCD2 je monoubikviniran kao odgovor na oštećenje DNK. Aktivirani protein FANCD2 kolokalizira se s BRCA1 (protein osjetljivosti na rak dojke) u žarištima izazvanim onizirajućim zračenjem i u sinaptonemskom kompleksu mejotskih hromosoma.
