NOD1 Overexpression Lysate

HEK293T cells in 10-cm dishes were transiently transfected with a non-lipid polymer transfection reagent specially designed and manufactured for large volume DNA transfection. Transfected cells were cultured for 48hrs before collection. The cells were lysed in modified RIPA buffer (25mM Tris-HCl pH7.6, 150mM NaCl, 1% NP-40, 1mM EDTA, 1xProteinase inhibitor cocktail mix, 1mM PMSF and 1mM Na3VO4, and then centrifuged to clarify the lysate. Protein concentration was measured by BCA protein assay kit.

Innate immunity is present in all animals and is the common mode of defense against microorganisms. It detects microorganisms by specific proteins called pattern-recognition molecules (PRMs) (reviewed in Werts et al. 2006). There is a limited set of PRMs in each animal genome, and it has been postulated that the PRMs were evolutionarily selected to detect conserved components or motifs of microorganisms called pathogen-associated molecular patterns (PAMPs). PAMPs are found in a wide range of microorganisms and recognition of PAMPs by PRMs activates inflammatory signaling pathways, thereby stimulating an immune response. NOD (nucleotide-binding oligomerization domain) proteins are a family of cytosolic proteins which have been implicated in innate recognition of bacteria, the induction of inflammatory responses, and the regulation of caspase activation and apoptosis. NOD1/CARD4 (caspase-recruitment domain 4 gene) is a PRM that recognizes specific peptidoglycan (PGN) components of bacterial cell walls (reviewed in Strober et al. 2006, and Inohara et al. 2003). NOD1 is expressed by cell types that are exposed to PGN under physiological conditions including antigen-presenting cells (APCs) such as macrophages and dendritic cells, and epithelial cells (reviewed in Strober et al. 2006). NOD1 is thought to play a role in the pathogenesis of human gastrointestinal disease and is associated with inflammatory bowel diseases and asthma. It is involved in host defense against Helicobacter pylori infection of the gastric mucosa, a chronic infection that can lead to peptic ulcers and gastric cancer. This antibody recognizes NOD1/CARD4. Human NOD1/CARD4 is a 953 amino acid protein.
