COUPTFII, or Nuclear receptor subfamily 2 group F member 2, is a human gene encoded by NR2F2. It may also be known as: COUP transcription factor 2; COUP-TF2; Apolipoprotein A-I regulatory protein 1; ARP-1; COUP transcription factor II; COUP-TF II; CHTD4; COUPTFB; NF-E3; NR2F1; SVP40; TFCOUP2; nuclear receptor subfamily 2, group F, member 2. The encoded protein has an amino acid length of 414 and a mass of 45.6 kDa. Other isoforms may exist. COUPTFII is a member of the Nuclear hormone receptor family, NR2 subfamily. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Chicken.
