RASSF family proteins are tumor suppressors that are frequently downregulated during the development of human cancer. RASSF6 (Ras association (RalGDS/AF-6) domain family member 6), a member of RASSF family, acts as a Ras effector protein / tumor suppressor. RASSF6 contains one Ras-associating domain and one SARAH domain. It is involved in the induction of apoptosis, through both caspase-dependent and caspase-independent pathways. Defects in RASSF6 may facilitate viral NFκ-B pathway and may play a vital role in infection.
