Overview
Glypican-4 (GPC4) is a member of the glypican family, a group of heparan sulfate proteoglycans that are anchored to the cell membrane via glycosylphosphatidylinositol (GPI). These proteins are critical for regulating various signaling pathways, including Wnt, Hedgehog, and bone morphogenetic protein (BMP) signaling. GPC4 is particularly important during embryonic development, where it influences tissue morphogenesis and organ formation. Research has also highlighted the role of GPC4 in cancer progression, as it may contribute to tumor growth and metastasis. Its ability to modulate signaling pathways makes it a potential target for therapeutic interventions. GPC4 is widely used in biomedical research, particularly in studies focusing on developmental biology and oncology.
Key Features
GPC4 is characterized by its heparan sulfate chains, which enable it to interact with a variety of signaling molecules. These interactions are essential for its role in modulating key developmental pathways. The protein’s GPI anchor allows it to be localized to the cell surface, where it can influence extracellular signaling events. Another distinguishing feature of GPC4 is its tissue-specific expression pattern. It is highly expressed in certain tissues during embryonic development but may also be re-expressed in tumors, suggesting a context-dependent role. This dual functionality makes GPC4 a protein of significant interest in both developmental biology and cancer research.
Application Areas
GPC4 is primarily used in research settings, particularly in studies investigating embryonic development and tissue regeneration. Its role in modulating signaling pathways makes it a valuable tool for understanding the molecular mechanisms underlying these processes. In cancer research, GPC4 is studied for its potential involvement in tumorigenesis and metastasis. Researchers are exploring its utility as a biomarker or therapeutic target. Additionally, GPC4 is used in drug discovery programs aimed at developing inhibitors or activators of its associated signaling pathways.
Precautions
When working with GPC4 in laboratory settings, it is essential to follow standard biosafety protocols. Proper handling and storage are required to maintain the protein’s stability and functionality. Researchers should use appropriate personal protective equipment (PPE) and adhere to institutional guidelines for working with biological materials. For procurement, it is advisable to source GPC4 from reputable suppliers who provide detailed documentation on purity, concentration, and origin. This ensures the reliability and reproducibility of experimental results.
B2B Procurement Guide
B2B buyers seeking GPC4 for research purposes should prioritize suppliers with a proven track record in providing high-quality recombinant proteins. Key considerations include the protein’s purity, activity, and endotoxin levels, as these factors can significantly impact experimental outcomes. It is also recommended to request batch-specific certificates of analysis (CoA) and technical support from suppliers. Pricing may vary based on quantity and supplier, so buyers should compare options and negotiate terms where possible. For large-scale purchases, establishing long-term partnerships with reliable suppliers can ensure consistent quality and availability.
