Funkcija

[uredi | uredi izvor]

Ovaj gen kodira alfa lanac kolagena tipa VII. Kolagensko vlakno tipa VII, sastavljeno od tri identična alfa-kolagenska lanca, ograničeno je na baznu zonu ispod slojevitog pločastog epitela. Funkcionira kao vlakno za sidrenje između vanjskog epitela i strome ispod. Mutacije u ovom genu su povezane sa svim oblicima distrofijska epidermolysis bullosa.[7] U odsustvu mutacija, međutim, autoimunski odgovor protiv kolagena tipa VII može dovesti do stečenog oblika ove bolesti koji se naziva epidermolysis bullosa acquisita.[8]

Kolagen tipa VII također nalazi se u retini; njegova funkcija u ovom organu nije poznata.[9]

COL7A1 nalazi se na kratkom kraku hromosoma 3, u regiji 3p21.31. Gen je veličine otprilike 31.000 baznih parova i izvanredan je po ekstremnoj fragmentaciji kodirajuće sekvence na 118 egzona.[10][11] COL7A1 se transkribira iu iRNK od 9.287 baznih parova.[12] U koži, kolagene proteine tipa VII sintetiziraju keratinociti i dermni fibroblasti.[13]

Simbol za ortologni gen kućnog miša je Col7a1.

Klinički značaj

[uredi | uredi izvor]

Nasljedna bolest, epidermolysis bullosa dystrophica, uzrokovana je dominantnim ili recesivnim mutacijama u COL7A1.[14]

Epidermolysis bullosa acquisita uključuje autoimunsku reakciju na ovaj oblik kolagena.[15]

Interakcije

[uredi | uredi izvor]

Pokazalo se da kolagen tipa VII alfa 1 ima interakcije sa lamininom 5[16] i fibronektinom.[17][18]
