Product Description |
Recombinant Human CD44 Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Gln21-Pro220 & Gln386-Ala427. |
Product Background |
CD44 is a hyaluronan binding cell surface signal transducing receptor that influences motility, cell survival and proliferation as well as the formation of tumor microenvironment. CD44 contains two variable regions encoded by variable exons. Alternative splicing, which is often deregulated in cancer, can produce various isoforms of CD44 with properties that may have different tissue specific effects and therefore even diverse effects on cancer progression |
