A number of ELISA Kits are available that target Small Proline-Rich Protein 1B, an alias of the protein, small proline rich protein 1B. The human protein, encoded by the gene SPRR1B, is a member of the Cornifin (SPRR) family. The protein's cellular localization is indicated to be cytoplasmic. Additional synonyms or past names for this protein may include: CORNIFIN, GADD33, SPR-IB, SPRR1. Homology is conserved in other species, such as Mouse, Rat.
