Function

EGF stimulates the growth of various epidermal and epithelial tissues in vivo and in vitro and of some fibroblasts in cell culture. Magnesiotropic hormone that stimulates magnesium reabsorption in the renal distal convoluted tubule via engagement of EGFR and activation of the magnesium channel TRPM6. Can induce neurite outgrowth in motoneurons of the pond snail Lymnaea stagnalis in vitro (PubMed:10964941).

Notes

Human EGF ELISA Kit (ab217772) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of EGF protein in cell culture supernatant, cit plasma, edta plasma, hep plasma, milk, saliva, serum, and urine. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human EGF with 1.04 pg/ml sensitivity.

SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:

- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips

A 384-well SimpleStep ELISA® microplate (Pre-coated 384 well Microplate SimpleStep ELISA® ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.

EGF precursor is a large 1185 amino acid group 1 member of the EGF family growth factors. All EGF family growth factors are synthesized as transmembrane proteins that undergo proteolytic processing to generate soluble forms. Human EGF is a 53 amino acid long fragment of the extracellular domain of EGF precursor. As other group 1 members, EGF binds to, and activates the EGF receptor. This promotes EGFR dimerization. EGF has variety of diverse physiological effects. EGF activity is complicated by the fact that other EGF family members utilize EGF receptor. EGF stimulates the growth of various epidermal and epithelial tissues in vivo and in vitro and of some fibroblasts in cell culture. EGF is proposed to affect growth and/or differentiation of many other fetal and adult tissues.

Activity summary

Epidermal Growth Factor (EGF) also known as urogastrone is a single polypeptide that facilitates cell growth proliferation and differentiation by binding to the Epidermal Growth Factor Receptor (EGFR). The EGF protein is characterized by a relatively small molecular weight of approximately 6.4 kDa. It is expressed in various tissues including the kidney submandibular glands and Brunner's glands in the mouse and other species. The presence of anti-EGF antibodies can further enhance the understanding of its mechanical actions and functions in different organisms.

Biological function summary

The epidermal growth factor plays a pivotal role in the regulation of cell signaling. It functions outside a complex interacting mainly with EGFR located on the cell surface. Upon ligand binding EGF induces the receptor dimerization leading to autophosphorylation which activates intrinsic intracellular signaling cascades. This activation is critical for cellular responses such as DNA synthesis and the progression of the cell cycle. EGF recombinant proteins such as HEGF are utilized in laboratories to examine its biological activity meticulously.

Pathways

EGF engages in key cellular pathways that mediate various essential functions. It significantly activates the MAPK and PI3K-AKT signaling pathways which govern processes such as cell division and survival. These pathways require the participation of several other proteins including Ras Raf and PDK1 which help modulate their downstream effects. The interplay of EGF with associated proteins highlights its importance in maintaining proper signaling dynamics necessary for healthy cellular function. EGF ELISA kits as well as EGF ELISAs are tools developed for robust analysis of its pathway interactions in research and clinical settings.

Associated diseases and disorders

Altered EGF signaling is associated with increased risk of certain cancers and inflammatory diseases. Overexpression or mutations in the EGF-EGFR axis can lead to the progression of carcinomas such as those found in the lung and breast as well as disorders like psoriasis. These aberrant signaling events are often linked with other proteins such as HER2 and VEGF which can exacerbate disease severity. The study and detection of EGF products therefore offer significant insights into both the progression and potential therapeutic targeting of these conditions.
