产品介绍 | Function : Receptor tyrosine kinase binding ligands of the EGF family and activating several signaling cascades to convert extracellular cues into appropriate cellular responses. Known ligands include EGF, TGFA/TGF-alpha, amphiregulin, epigen/EPGN, BTC/betacellulin, epiregulin/EREG and HBEGF/heparin-binding EGF. Ligand binding triggers receptor homo- and/or heterodimerization and autophosphorylation on key cytoplasmic residues. The phosphorylated receptor recruits adapter proteins like GRB2 which in turn activates complex downstream signaling cascades. Activates at least 4 major downstream signaling cascades including the RAS-RAF-MEK-ERK, PI3 kinase-AKT, PLCgamma-PKC and STATs modules. May also activate the NF-kappa-B signaling cascade. Also directly phosphorylates other proteins like RGS16, activating its GTPase activity and probably coupling the EGF receptor signaling to the G protein-coupled receptor signaling. Also phosphorylates MUC1 and increases its interaction with SRC and CTNNB1/beta-catenin. Isoform 2 may act as an antagonist of EGF action. 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. This product is an active protein and may elicit a biological response in vivo, handle with caution. 重组人表皮生长因子rhEGF,是人生长因子中的一种,是由53个氨基酸组成的相对分子量为6.2KDa的小分子多肽。重组人表皮生长因子作为一种强有力的细胞分裂因子,具有多种生物活性。 主要表现为: 1、在体内刺激皮肤组织、角膜和气管上皮组织的生长繁殖; 2、加速角膜、皮肤等表皮创伤的修复; 3、抑制胃酸分泌; 4、促进人皮肤上皮细胞、角膜上皮细胞、哺乳动物上皮细胞生长; 5、增强表皮细胞的蛋白质、DNA、RNA的合成和细胞代谢等。 重组人表皮生长因子不仅具有促进皮肤和黏膜创伤的愈合,防治溃疡以及消炎镇痛的作用,而且能有效促进和调节表皮细胞的生长和增殖,表皮细胞生长因子对保护和疗养皮肤、黏膜具有十分独特的功效。广泛应用于治疗烧伤、烫伤、手术伤、机械伤、皮肤溃疡、激光美容等。 重组人表皮生长因子在护肤保健化妆品中也具有广泛的应用价值和市场前景。重组人表皮生长因子在护肤保健化妆品中的作用如下: ①嫩肤护肤作用。重组人表皮生长因子能促进皮肤细胞对营养物质的吸收,加速细胞的新陈代谢,促进皮肤细胞的分裂和增长,促进透明质酸和糖蛋白的合成。 ②促进细胞再生和组织修复。重组人表皮生长因子有促进皮肤和黏膜创伤面的愈合作用,并减少疤痕挛缩和皮肤畸形增生。用于治疗疤痕,尤其是痤疮后遗的疤痕疙瘩疗效较好。 ③防晒作用。重组人表皮生长因子能促进新生细胞的生长,替代受紫外线照伤的细胞,以降低皮肤中黑色素细胞的数量。 重组人表皮生长因子在化妆品中应用具有很好的安全性、经济性。临床实验发现重组人表皮生长因子虽然能很快诱导皮肤细胞中多角形细胞增殖,但经过一段时间后便达到生理平衡,细胞不再无限增殖,即表皮生长因子具有使皮肤细胞更新又不导致细胞畸型的特性。 重组人表皮生长因子价格虽然较昂贵,但它的作用剂量小只要有10-9克数量级的表皮生长因子存在就可发挥相应的功能,所以该类产品性能价格比极佳 |
