Funkcija
Protein kodiran ovim genom pripada porodici lin-28, koju karakterizira domen hladnog šoka i para CCHC domen cinkovog prsta. Ovaj gen je visoko eksprimiran u sjemenicima, fetusnoj jetri, posteljici, te u primarnim ljudskim tumorima i linijama ćelija raka. Negativno je reguliran preko miRNK koje cilja na mjesta u 3'UTR, a prekomjerna ekspresija ovog gena u primarnim tumorima povezana je s potiskivanjem porodičn ih let-7 mikroRNK i uklanjanje depresije ciljeva let-7, što olakšava ćelijsku transformaciju.
