Recombinant Human Cornulin

Synonyms SEP53, DRC1, PDRC1, Cornulin, Tumor-related protein, Squamous epithelial heat shock protein 53, 53 kDa squamous epithelial-induced stress protein, 58 kDa heat shock protein, 53 kDa putative calcium-binding protein, CRNN, C1orf10.

Introduction CRNN is part of the "fused gene" family of proteins, which enclose N-terminus EF-hand domains and multiple tandem peptide repeats. CRNN contains two EF-hand Ca2+ binding domains in its N-terminus and two glutamine- and threonine-rich 60 amino acid repeats in its C-terminus. CRNN, also known as SEP53, which participates in the mucosal/epithelial immune response and epidermal differentiation. CRNN is a survival factor that participates in the clonogenicity of squamous esophageal epithelium cell lines, attenuates deoxycholic acid (DCA)-induced apoptotic cell death and discharge of calcium. When CRNN is over expressed in oral squamous carcinoma cell lines, it regulates negatively cell proliferation by the induction of G1 arrest.

Recombinant Human CornulinDescription CRNN Human Recombinant fused to 20 amino acid His Tag at N-terminal produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 515 amino acids (1-495 a.a.) and having a molecular mass of 55.7 kDa. The CRNN is purified by proprietary chromatographic techniques.

Source Escherichia Coli.

Physical Appearance Sterile Filtered clear colorless solution.

Formulation The CRNN solution contains 20mM Tris-HCl pH-8 and 10% glycerol.

Stability CRNN Recombinant Human although stable at 4°C for 30 days, should be stored desiccated below -20°C for periods greater than 30 days. Please avoid freeze-thaw cycles.
