INO80B encodes the human gene, INO80 complex subunit B. It may also be known as: High mobility group AT-hook 1-like 4; IES2 homolog; hIes2; PAP-1-associated protein 1; PAPA-1; Zinc finger HIT domain-containing protein 4; PAP-1 binding protein; IES2 homolog (S. cerevisiae); HMGA1L4; HMGIYL4; IES2; PAP-1BP; ZNHIT4. The encoded protein has an amino acid length of 356 and a mass of 38.6 kDa. Other isoforms may exist. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
