Principle of the Assay: The OmniKine Human EGFR ELISA Kit contains the components necessary for quantitative determination of natural or recombinant Human EGFR concentrations within any experimental sample including cell lysates, serum and plasma. This particular immunoassay utilizes the quantitative technique of a "Sandwich" Enzyme-Linked Immunosorbent Assay (ELISA) where the target protein (antigen) is bound in a "sandwich" format by the primary capture antibodies coated to each well-bottom and the secondary detection antibodies added subsequently by the investigator. The capture antibodies coated to the bottom of each well are specific for a particular epitope on Human EGFR while the user-added detection antibodies bind to epitopes on the captured target protein. Amid each step of the procedure, a series of wash steps must be performed to ensure the elimination of non-specific binding between proteins to other proteins or to the solid phase. After incubation and "sandwiching" of the target antigen, a peroxidase enzyme is conjugated to the constant heavy chain of the secondary antibody (either covalently or via Avidin/Streptavidin-Biotin interactions), allowing for a colorimetric reaction to ensue upon substrate addition. When the substrate TMB (3, 3', 5, 5'-Tetramethylbenzidine) is added, the reaction catalyzed by peroxidase yields a blue color that is representative of the antigen concentration. Upon sufficient color development, the reaction can be terminated through addition of Stop Solution (2 N Sulfuric Acid) where the color of the solution will turn yellow. The absorbance of each well can then be read by a spectrophotometer, allowing for generation of a standard curve and subsequent determination of protein concentration!!Background/Introduction: Human EGF receptor is not only a cell surface receptor for EGF, but also for other members of the EGF family, such as TGF-alpha, BTC/betacellulin, AREGAREGB/amphiregulin, HBEGF, GP30 and vaccinia virus growth factor. Ligand binding triggers a conformation change, leading to activation of the kinase and subsequent phosphorylation of down-stream protein kinases. Hence, EGF receptor is involved in the control of cell growth, proliferation and differentiation. Such receptor also phosphorylates MUC1 in breast cancer cells and increases the interaction of MUC1 with SRC and CTNNB1/beta-catenin. EGF binding triggers dimerization of the receptor and promotes auto-phosphorylation. The activate receptor dimer binds one EGF molecule while the heterodimer binds with ERBB2 and interacts with ERRFI1. Interaction with ERRFI1 inhibits dimerization of the kinase domain and auto-phosphorylation. ERRFI1 bounded EGF receptor also binds with RIPK1 and interacts with CBL via the auto-phosphorylated C-terminal tail. EGF receptor is part of a complex with ERBB2 and either PIK3C2A or PIK3C2B that may indirectly interact in the auto-phosphorylated form with PIK3C2B. Upon EGF treatment, the ligand bounded receptor complex also interacts with PELP1, binds with MUC1, interacts with AP2M1, interacts with GAB2, and interacts with COPG. These interactions are essential for regulation of EGF-dependent nuclear transport of EGFR by retrograde trafficking from the Golgi to the ER. In addition, EGF receptor interacts with FER and TNK2. Such interaction is dependent on EGF stimulation and kinase activity of EGFR. EGF receptor phosphorylation of Ser-695 is partial and occurs only if Thr-693 is phosphorylated. Monoubiquitinated and polyubiquitinated occur upon EGF stimulation, which does not affect tyrosine kinase activity or signaling capacity, but may play a role in lysosomal targeting. Polyubiquitin linkage is mainly through 'Lys-63' while linkage through 'Lys-48', 'Lys-11' and 'Lys-29' also occur. Studies have shown that defects in EGFR are associated with lung cancer.

NCBI Description

The protein encoded by this gene is a membrane glycoprotein that mediates cell-cell signaling and plays a critical role in the growth and development of multiple organ systems. An extraordinary variety of different isoforms are produced from this gene through alternative promoter usage and splicing. These isoforms are expressed in a tissue-specific manner and differ significantly in their structure, and are classified as types I, II, III, IV, V and VI. Dysregulation of this gene has been linked to diseases such as cancer, schizophrenia, and bipolar disorder (BPD). [provided by RefSeq, Apr 2016]

Uniprot Description

NRG1: Direct ligand for ERBB3 and ERBB4 tyrosine kinase receptors. Concomitantly recruits ERBB1 and ERBB2 coreceptors, resulting in ligand-stimulated tyrosine phosphorylation and activation of the ERBB receptors. The multiple isoforms perform diverse functions such as inducing growth and differentiation of epithelial, glial, neuronal, and skeletal muscle cells; inducing expression of acetylcholine receptor in synaptic vesicles during the formation of the neuromuscular junction; stimulating lobuloalveolar budding and milk production in the mammary gland and inducing differentiation of mammary tumor cells; stimulating Schwann cell proliferation; implication in the development of the myocardium such as trabeculation of the developing heart. Isoform 10 may play a role in motor and sensory neuron development. The cytoplasmic domain interacts with the LIM domain region of LIMK1. Interacts with ERBB3 and ERBB4. Type I isoforms are the predominant forms expressed in the endocardium. Isoform alpha is expressed in breast, ovary, testis, prostate, heart, skeletal muscle, lung, placenta liver, kidney, salivary gland, small intestine and brain, but not in uterus, stomach, pancreas, and spleen. Isoform 3 is the predominant form in mesenchymal cells and in non-neuronal organs, whereas isoform 6 is the major neuronal form. Isoform 8 is expressed in spinal cord and brain. Isoform 9 is the major form in skeletal muscle cells; in the nervous system it is expressed in spinal cord and brain. Also detected in adult heart, placenta, lung, liver, kidney, and pancreas. Isoform 10 is expressed in nervous system: spinal cord motor neurons, dorsal root ganglion neurons, and brain. Predominant isoform expressed in sensory and motor neurons. Not detected in adult heart, placenta, lung, liver, skeletal muscle, kidney, and pancreas. Not expressed in fetal lung, liver and kidney. Type IV isoforms are brain-specific. Belongs to the neuregulin family. 10 isoforms of the human protein are produced by alternative splicing.
