Purity > 90% as determined by SDS-PAGE. MW: 23.9kDa. Full Length of Mature Protein: 29-210aa. N-terminal 6xHis-tagged. Mus musculus (Mouse). Stimulates glucose uptake in differentiated adipocytes via the induction of glucose transporter SLC2A1/GLUT1 expression (but not SLC2A4/GLUT4 expression). Activity probably requires the presence of KLB.
