GPNMB HEK Recombinant Protein

Source : HEK 293. GPNMB Human Recombinant produced in HEK cells is a single, glycosylated, polypeptide chain (a.a 22-486) containing a total of 477 amino acids, having a molecular mass of 53.7kDa (calculated), though it migrates at approximately 97kDa on SDS PAGE, the GPNMB is fused to a 2 a.a C-terminal linker and a 10 a.a His tag at C-Terminus.The Human GPNMB is purified by proprietary chromatographic techniques. Glycoprotein Nmb (GPNMB) is a member of the PMEL/NMB family. GPNMB is a type I transmembrane glycoprotein which exhibits homology to the pMEL17 precursor, a melanocyte-specific protein. GPNMB is expressed in the lowly metastatic human melanoma cell lines and xenografts but has no expression in the highly metastatic cell lines. GPNMB might be involved in growth delay and reduction of metastatic potential. GPNMB is up-regulated in a number of cancer cells, including in glioblastoma multiforme. GPNMB is expressed in many melanoma cells, as well as in tissue macrophages, including liver Kuppfer cells and lung alveolar macrophages, in podocytes and in some cells of the ciliary body of the eye (at protein level) . GPNMB is hardly detectable in the healthy brain.
