ZNFX1 is a 1918 amino acid nuclear protein that is widely expressed and contains six NF-X1-type zinc fingers, which are presumed to function as zinc binding domains. The gene encoding ZNFX1 maps to human chromosome 20, which contains nearly 63 million bases that encode over 600 genes, some of which are associated with Creutzfeldt-Jakob disease, amyotrophic lateral sclerosis, spinal muscular atrophy, ring chromosome 20 epilepsy syndrome and Alagille syndrome. There are two isoforms of ZNFX1 that are produced as a result of alternative splicing events.
