Funkcija
urediFANCF je adapterski protein koji ima ključnu ulogu u pravilnom sklapanju kompleksa jezgra FA.[7] Kompleks jezgre FA sastoji se od osam proteina (FANCA, FANCB, -FANCC, FANCE, FANCF, FANCG, FANCL i FANCM).[8][9] FANCF stabilizira interakciju između potkompleksa FANCC/FANCE i potkompleksa FANCA/FANCG i zaključava cijeli kompleks jezgra FA u konformaciju koja je neophodna za obavljanje svoje funkcije u popravci DNK.[7]
Kompleks jezgra FA je kompleks jedarnog jezgra koji je neophodan za monoubikvitinaciju FANCD2 i ovaj modifikovani oblik FANCD2 kolokalizuje se sa BRCA1, RAD51 i PCNA u fokusima koji također sadrže druge proteine za popravku DNK.[7] Sve ovi proteini funkcionišu zajedno kako bi olakšali popravku umrežene veze između DNK. Također funkcionišu u drugim procesima popravke odgovora na oštećenje DNK, uključujući oporavak i stabilizaciju zaustavljenih replikacijskih viljuški.[9] FoxF1 protein također stupa u interakciju sa jezgrom FA proteina i inducira njegovo vezivanje za hromatin, kako bi promovirao popravak DNK.[9]
Čini se da je oštećenje DNK primarni uzrok raka,[10] a čini se da su nedostaci u ekspresiji gena za popravku DNK u osnovi mnogih oblika raka[].[11][12] Ako je popravak DNK nedovoljan, oštećenje DNK ima tendenciju da se akumulira. Takvo prekomjerno oštećenje DNK može povećati mutacije zbog sklonosti greškama translezijske sinteze. Prekomjerno oštećenje DNK također može povećati epigenetičke promjene zbog grešaka tokom popravke DNK.[13][14] Takve mutacije i epigenetske promjene mogu dovesti do raka.
Smanjenje ekspresija gena za popravku DNK (obično uzrokovano epigenetičkim promjenama) vrlo je uobičajeno kod karcinoma, i najčešće je mnogo češće od mutacijskih defekata u genima za popravku DNK kod karcinoma.
Metilacija promotorske regije gena FANCF uzrokuje smanjenu ekspresiju proteina FANCF.[15]
Učestalosti metilacije promotora FANCF u nekoliko različitih karcinoma prikazane su u tabeli.
| Kancer | Učestalost | Referenca |
|---|---|---|
| Epitelni rak jajnika | 32% | [16] |
| Rak grlića maternice | 30% | [17] |
| Rak jajnika | 21%-28% | [15][18] |
| Skvamozni karcinom glave i vrata | 15% | [19] |
| Rak pluća nemalih ćelija | 14% | [19][20] |
| Tumor muških germinativnih ćelija | 6% | [21] |
Kod invazivnih karcinoma dojke, mikroRNK-210 (miR-210) je povećana, zajedno sa smanjenom ekspresijom FANCF, gdje je FANCF bio jedna od vjerojatnih meta miR-210.[22]
Iako se mutacije u "FANCF" obično ne primjećuju u ljudskim tumorima, mišji model s nedostatkom "FANCF" bio je sklon raku jajnika.[23]
Čini se da je FANCF jedan od oko 26 gena za popravku DNK koji su epigenetski potisnuti kod različitih karcinoma (vidi Epigenetika raka).
Gonadni FANCF mutantnih miševa funkcionišu abnormalno, kompromitujući razvoj folikula i spermatogenezu kao što je uočeno na drugim modelima mišje Fanconijeve anemije i Fanconijevom anemijom pacijenata.[23] Histološki pregled testisa kod miševa s nedostatkom FANCF-a pokazao je da su seminferni tubuli lišeni klicnih ćelija. U dobi od 14 sedmica, ženke miševa s nedostatkom FANCF-a bile su gotovo ili potpuno lišene primordijalnih folikula. Zaključeno je da miševi s nedostatkom FANCF-a pokazuju brzo iscrpljivanje primordijalnih folikula u mladoj dobi, što rezultira uznapredovalim jajnika.[23]
Interakcije
urediPokazalo se da FANCF reaguje sa FANCA,[7][24] FANCG,[7][24][25][26] FANCA[7][24][27] i FANCE.[7][28]
