Snep, or Sushi, nidogen and EGF-like domains 1, is a human gene encoded by SNED1. It may also be known as: Sushi, nidogen and EGF-like domain-containing protein 1; IRE-BP1; Insulin-responsive sequence DNA-binding protein 1; SST3. The encoded protein has an amino acid length of 1413 and a mass of 152.2 kDa. Other isoforms may exist. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
