Funkcija
[uredi | uredi izvor]Proizvod ovog gena pripada porodici Ras-srodnih proteina. Ovi proteini dijele približno 50% aminokiselinskog identiteta s klasičnim RAS proteinima i imaju brojne zajedničke strukturne karakteristike. Najupečatljivija razlika između RAP proteina i RAS proteina je u njihovoj 61. aminokiselini: glutamin u RAS je zamijenjen treoninom u RAP proteinima. Proizvod ovog gena suprotstavlja se mitogenoj funkciji RAS-a jer može komunicirati sa RAS GAP-ovima i RAF-om na kompetitivni način. Za ovaj gen su identificirane dvije varijante transkripta koje kodiraju isti protein.[7]
