Gain-of-function mutations in KIT a member of the receptor type tyrosine kinases are observed in certain neoplasms including mast cell tumors (MCTs) and acute myelogenous leukemias (AMLs). he receptor tyrosine kinase KIT regulates mast cell growth differentiation and survival1. When the KIT ligand stem cell factor (SCF) binds to this receptor KIT dimerizes autophosphorylates and… Continue reading Gain-of-function mutations in KIT a member of the receptor type tyrosine
