產品英文名稱: WNT-5a, Human
產品中文名稱:人重組WNT-5a蛋白

WNT-5a, Human產品介紹:
Wnt信號轉導通路因其啟動蛋白為Wnt蛋白而得名，在胚胎發(fā)育、細胞增殖及分化等方面發(fā)揮重要 作用，其異?；罨c人類多種腫瘤的發(fā)生密切相關。研究顯示，Wnt信號至少存在經(jīng)典和非經(jīng)典兩條不同的信號通路，而Wnt-5a屬于非經(jīng)典Wnt信號通路，既往研究Ror2具有Wnt受體結構域樣結構。有研究認為Wnt-5a經(jīng)由Ror2介導的 信號通路發(fā)揮作用。
Human WNT-5a蛋白含有357個氨基酸殘基。

WNT-5a, Human產品英文簡述:
WNT-5a belongs to the class of WNT proteins that activate the “noncanonical” pathway. The predicted size of human WNT-5a is a monomeric protein containing 357 amino acid residues. Due to glycosylation, it migrates at an apparent molecular weight of ~45 kDa on SDS-PAGE under non-reducing conditions. StemRD’s product is expressed from a human cell line in animal-free medium, and purified with a proprietary process that is distinct from the published method.

? Purity: Greater than 85% as determined by SDS-PAGE and HPLC analysis
? Biological Activity: The activity was determined by using a TCF reporter gene assay in HEK293 cells co-transfected with Frizzled-4 and LRP-? 5. WNT-5a activates (instead of inhibits) the TCF reporter gene in this assay (MilkelsAJ, et al., PLoS Biol, 4:e115, 2006). This activation mode is utilized because activation assays are generally more reliable than inhibition assays, as they are less prone to any non-specific inhibitory contamination in the preparation.
