产品说明

应用

Thrombopoietin from mouse can be used in a genetic screening test for examining the role of somatic activating mutations in EPOR, MPL, or GCSFR genes in activating myeloproliferative disorders (MPD) in JAK2V617F-negative MPD patients.

生化/生理作用

Thrombopoeitin (TPO), also known as the ligand for the c-mpl proto-oncogene (Mpl-L) and as megakaryocyte colony stimulating factor (Meg-CSF), is a primary regulatory factor for megakaryocytopoiesis and thrombopoiesis. Produced mainly by hepatocytes but also by kidney cells, TPO is a humoral glycoprotein that stimulates growth and maturation of megakaryocytes and megakaryocytic colonies from bone marrow cultures. TPO binds and activates an 68-78 kDa glycoprotein receptor belonging to the GH family of cytokine receptors, a family that includes receptors to growth hormone (GH), erythropoietin (EPO) and prolactin (PRL). Like GH and EPO, TPO may bind to its receptor at two distinct sites, initiating receptor dimerization and activation. Analysis of mRNA indicates also the existence of a novel truncated and potentially soluble form of TPO receptor. The viral oncogene v-mlp of the myeloproliferative leukemia virus (MPLV) contains the gene sequence for the entire cytoplasmic and transmembrane domains and a portion of the extracellular domain of c-mlp (TPO receptor). TPO receptors are found on megakaryocytes and their precursors and on platelets. The mature form of TPO is a highly conserved glycoprotein, showing approximately 70% sequence homology among various mammals. Human TPO contains 332 amino acids (mouse 335) including two internal disulfide bonds and 6 N-linked glycosylation sites (mouse 7). The N-terminal 153 amino acid region of TPO shows structural and amino acid sequence homology to erythropoietin and a pair of arginines (potential cleavage site) separating it from the highly glycosylated carboxyterminal domain.
Thrombopoietin from mouse is an amino acid peptide that plays a pivotal role in megakaryocyte proliferation and differentiation. It also serves as a growth factor for liver endothelial cells in mouse.
