Funkcija

Ku70 i Ku80 zajeno čine Ku heterodimer, koji se vezuje za krajeve dvolančanog prekida DNK i potreban je za put popravka DNK nehomolognim spajanjem krajevaa (NHEJ). Također potreban je za V(D)J rekombinaciju, koja koristi NHEJ put za promoviranje raznolikosti antigena u imunskom sistemu sisara.

Osim svoje uloge u NHEJ, Ku je također potreban za održavanje dužine telomere i utišavanje subtelomernih gena.^[7]

Ku je prvobitno identificiran kada je otkriveno da pacijenti sa sistemskim eritemskim lupusom imaju visok nivo autoantitijela na protein.^[5]

Starenje

Mišje embrionske matične ćelije sa homozigotnim Ku70 mutacijama, odnosno Ku70^–/– ćelije , imaju značajno povećanu osetljivost na ionizirajuće zračenje u poređenju sa heterozigotnim Ku70^+/– ili divljim tipom Ku70 ^+/+ embrionskih matičnih ćelija.^[8] Mutantni miševi s nedostatkom Ku70 imaju rano starenje.^[9] Koristeći nekoliko specifičnih kriterija starenja, otkriveno je da mutantni miševi pokazuju iste znakove starenja kao kontrolni miševi, ali u znatno ranijoj hronološkoj dobi. Ovi rezultati sugeriraju da smanjena sposobnost popravljanja dvostrukih lanaca DNK uzrokuje rano starenje i da divlji tip gena Ku70 ima važnu ulogu u osiguranju dugovječnosti.^[10]

Klinički značaj

Mutacija ovog gena je opisana u skupu od 24 porodice sa autizmom.^[11] Iako ovo sugeriše da ovaj gen može imati ulogu u razvoju autizma, potrebno je dalje istraživanje.

Nomenklatura

Ku70 se pominje sa nekoliko imena uključujući:
