基本信息
| NACRES | NA.32 |
| General description【一般描述】 | The gene IGFBP4 (insulin-like growth factor-binding protein 4) is mapped to human chromosome 17q21. It belongs to the IGFBP family of proteins. The protein has a IGF (insulin-like growth factor)-binding site and a thyroglobulin type-1 domain. IGFBPs are mainly required to regulate IGFs activities. IGFBP4 can be cleaved by PAPP-A (pregnancy-associated plasma protein-A) in IGF-dependent mechanism. Recombinant human IGF-BP4 is a 25.7kDa protein consisting of 237 amino acid residues including the IGF-BP domain and thyroglobulin type-I domain. |
| Application【应用】 | IGF-Binding Protein 4 human has been used to check the dependency of FSH (follicle-stimulating hormone) action in human Cumulus granulosa cells on IGF-2 (insulin-like growth factor 2). |
| Biochem/physiol Actions【生化/生理作用】 | IGFBP4 (insulin-like growth factor-binding protein 4) suppresses cell proliferation and DNA synthesis and induces cell death. IGFBP4 participates in adipose tissue expandability and interacts with IGF1 (insulin-like growth factor 1). Interaction with IGF1 disrupts mitogenic signaling. IGFBP4 is suggested as a serum biomarker of Lupus Nephritis and is associated with the chronicity of renal pathology in patients. IGFBP4 is also linked with cardiovascular death in type 1 diabetes patients in the absence/presence of nephropathy. It is also linked with the progression of tumors. |

| Physical form【外形】 | Lyophilized from 1x PBS, pH 7.2. |
| Reconstitution【重悬】 | Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8℃ for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20℃ to -80℃. |
