Afadin is a protein that in humans is encoded by the MLLT4 gene.[1]

AF6 is a Ras (see HRAS; MIM 190020) target that regulates cell–cell adhesions downstream of Ras activation. It is fused with MLL (MIM 159555) in leukemias caused by t(6;11) translocations (Taya et al., 1998).[supplied by OMIM][2]

Interactions[edit]

MLLT4 has been shown to interact with F11 receptor,[3] RAP1A,[4] LMO2,[5] EPHB3,[6] RAP1GAP,[7] PVRL1,[8] PVRL3,[9][10] USP9X,[11][12] SORBS1,[13] BCR gene,[14] Tight junction protein 1,[15] Profilin 1,[4] HRAS[4][15] and SSX2IP.[16]
