RASSF3 (Ras Association Domain Family Member 3) is a Protein Coding gene. GO annotations related to RASSF3 include identical protein binding. An important paralog of RASSF3 is RASSF5. The RAS oncogene is mutated in nearly one-third of all human cancers. Members of the RAS superfamily are plasma membrane GTP-binding proteins that modulate intracellular signal transduction pathways. A subfamily of RAS effectors, including RASSF3, share a RAS association (RA) domain.
