NFIX encodes the human gene, Nuclear factor I/X (CCAAT-binding transcription factor). It may also be known as: Nuclear factor 1 X-type; NF1-X; Nuclear factor 1/X; Nuclear factor I/X; NF-I/X; NFI-X; MRSHSS; NF1A; SOTOS2. The encoded protein has an amino acid length of 502 and a mass of 55.1 kDa. Other isoforms may exist. NFIX is a member of the CTF/NF-I family. Homologs of this gene exist in other organisms, including: Mouse, Zebrafish.
