The C-MPL Protein, a receptor for thrombopoietin, is a protein encoded in humans by the oncogene of myeloproliferative leukemia virus. The C-MPL Protein is involved in the activation of the JAK/STAT/MAPK signaling pathway. C-MPL Protein is a biomarker for thrombocytopenia. C-MPL Protein, Rat (HEK293, Fc) is the recombinant rat-derived C-MPL protein, expressed by HEK293 , with C-hFc labeled tag.
