Family with sequence similarity 98, member A, or FAM98A, is a gene that in the human genome encodes the FAM98A protein. FAM98A has two paralogs in humans, FAM98B and FAM98C. All three are characterized by DUF2465, a conserved domain shown to bind to RNA.[5] FAM98A is also characterized by a glycine-rich C-terminal domain.[6] FAM98A also has homologs in vertebrates and invertebrates and has distant homologs in choanoflagellates and green algae.
