Funkcija

uredi

Iako je USP53 klasifikovan kao deubikvitinirajući enzim na osnovu homologije sekvence sa drugim proteazama iz ove grupe, nedostaje mu funkcionalno esencijalni histidin u katalitičkom domenu, a testovi aktivnosti ukazuju na to da je USP53 katalitski neaktivan.[7][8][9] Iako je USP53 lišen katalitske aktivnosti, USP53 služi važnim fiziološkim funkcijama:

  • pokazalo se da mutacije u Usp53 uzrokuju progresivni gubitak sluha kod miševa,[9] kao i kasni gubitak sluha i holestazu kod ljudi.[10]

USP53 nalazi se na ćelijskim uskim spojevima i stupa u interakciju s proteinom čvrstih spojeva 2 (TJP2).[9] Mutacije TJP2 uzrokuju smetnje u čulu sluha[11] i holestazu.[12]
