THPO (human)

Overview
THPO Lineage-specific cytokine affecting the proliferation and maturation of megakaryocytes from their committed progenitor cells. It acts at a late stage of megakaryocyte development. It may be the major physiological regulator of circulating platelets. Defects in THPO are the cause of thrombocythemia type 1 (THCYT1). A myeloproliferative disorder characterized by elevated platelet levels due to sustained proliferation of megakaryocytes, and frequently lead to thrombotic and haemorrhagic complications. Belongs to the EPO/TPO family. 3 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
