EPG4, or Etoposide induced 2.4, is a human gene encoded by EI24. It may also be known as: Etoposide-induced protein 2.4 homolog; p53-induced gene 8 protein; ectopic P-granules autophagy protein 4 homolog (C. elegans); PIG8; TP53I8. The encoded protein has an amino acid length of 340 and a mass of 39.0 kDa. Other isoforms may exist. EPG4 is a member of the EI24 family. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
