The RGMB protein is a member of the repulsion guidance molecule (RGM) family and plays a critical role in the developing nervous system by enhancing bone morphogenetic protein (BMP) signaling. As a BMP coreceptor, RGMB promotes neuronal adhesion and may inhibit neurite outgrowth. RGMB Protein, Human (HEK293, His) is the recombinant human-derived RGMB protein, expressed by HEK293 , with C-His labeled tag.
