Vertebrate FUS2 genes, which are known to be putative tumor suppressor gene, contain several important domains such as the catalytic N-acetyltransferase (NAT) domain. NAT domain is essential enzymes involved in several sophisticated cellular processes such as N-acetylation, O-acetylatin. NAT enzymes may be involved in susceptibility to cancer including colorectal cancer because of the presence of carcinogenic heterocyclic amines in some cooked foods. FUS2 was physically localized to the cytoplasm. Also, FUS2 showed the actin dependent movement, closely related to the polarization in the budding yeast, Saccharomyces cerevisiae.
