CRNN encodes the human gene, Cornulin. It may also be known as: 53 kDa putative calcium-binding protein; 53 kDa squamous epithelial-induced stress protein; 58 kDa heat shock protein; Squamous epithelial heat shock protein 53; Tumor-related protein; C1orf10; PDRC1; 19603. The encoded protein has an amino acid length of 495 and a mass of 53.5 kDa. CRNN is a member of the S100-fused protein family. Homologs of this gene exist in other organisms, including: Mouse, Rat, Chicken.
