| Background Information | Transmembrane and immunoglobulin domain-containing protein 1 (UniProt Q6UXZ0) is encoded by the TMIGD1 (also known as TMIGD) gene (ORF UNQ9372/PRO34164; Gene ID 388364) in human. TMIGD1 protein is an adhesion molecule expressed in renal tubular epithelial cells and is highly conserved between human and murine species. TMIGD1 regulates renal epithelial cell trans-epithelial electric resistance, permeability, migration and cell morphology, and protects renal epithelial cells from oxidative stress and nutrient deprivation-induced injury. Hydrogen peroxide is shown to induce TMIGD1 ubiquitination and degradation. In addition, TMIGD1 expression is downregulated in mouse acute kidney injury (AKI) and in deoxy-corticosterone acetate (DOCA) and sodium chloride (DOCA-salt)-induced chronic hypertensive kidney disease models. TMIGD1 is produced with a signal peptide sequence (a.a. 1-29), the removal of which yields the mature single-transmembrane (a.a. 221-241) protein with a large extracellular region (a.a. 30-220) and a short cytoplasmic tail (a.a. 242-262). The extracellular region contains two C2-type Ig-like domains (a.a. 30-114 & 122-207) that mediate TMIGD1 dimerization. |

| Key Applications |
|
| Application Notes | Western Blotting Analysis: A 1:500 dilution from a representative lot detected TMIGD1 in 10 µg of human kidney tissue lysate and Raji membrane extract. Western Blotting Analysis: A representative lot detected the overexpression of a c-myc tagged murine TMIDG1 in transfected HEK-293 cells, as well as the endogenous TMIDG1 in mock-transfected HEK-293 cells. Immunogen peptide blocking abolished the target band (Arafa, E., et al. (2015). Am. J. Pathol. In press). Western Blotting Analysis: A representative lot detected a downregulated TMIGD1 level in HK-2 (human kidney 2) proximal tubular cells following TMIGD1 siRNA transfection or hydrogen peroxide treatment. Pretreatment with proteasome inhibitor Bortezomib (Cat. No. 504314) prevented H2O2-induced TMIGD1 downregulation (Arafa, E., et al. (2015). Am. J. Pathol. In press). Western Blotting Analysis: A representative lot detected a ~45 kDa glycosylated TMIGD1 band in untreated HK-2 (human kidney 2) proximal tubular cell lysate, as well as a ~29 kDa deglycosylated TMIGD1 band in PNGase-F-treated HK-2 cell lysate (Arafa, E., et al. (2015). Am. J. Pathol. In press). Immunohistochemistry Analysis: A representative lot detected a high TMIGD1 expression in mouse kidney proximal and distal tubular cells, while little TMIGD1 immunoreactivity was seen in podocytes (Arafa, E., et al. (2015). Am. J. Pathol. In press). Immunoprecipitation Analysis: A representative lot immunoprecipitated highly ubiquitinated TMIGD1 from hydrogen peroxide-treated HK-2 (human kidney 2) proximal tubular cells (Arafa, E., et al. (2015). Am. J. Pathol. In press). Immunocytochemistry Analysis: A representative lot detected the overexpression of a c-myc-tagged murine TMIDG1 in transfected HEK-293 cells by fluorescent immunocytochemistry staining (Arafa, E., et al. (2015). Am. J. Pathol. In press). |
