The function of this gene has not yet been determined but may involve a role in tumor suppression. Alternative splicing of this gene results in several transcript variants; however, most of the variants have not been fully described. RASSF4 (Ras Association Domain Family Member 4) is a Protein Coding gene. Among its related pathways are Hippo signaling pathway -multiple species. An important paralog of this gene is RASSF2.
