Recombinant Human Fms-Related Tyrosine Kinase 3, His-tagged

Cat. No.: FLT3-545H
Product Overview: Recombinant human FLT3 was expressed by baculovirus inSf9 cells usingan N-terminal His tag. MW=54.2kDa.
Description: FLT3 is a receptor tyrosine kinase that has been shown to play a role in proliferation and survival of hematopoietic progenitor cells as well as differentiation of early B lymphoid progenitors. FLT3 consists of an extracellular domain composed of five immunoglobulin-like domains, one transmembrane region, and a cytoplasmic kinase domain split into two parts by a kinase-insert domain. FLT3 is the most frequently mutated gene in cases of acute myelogenous leukemia (AML). About 30 to 35% of patients have either internal tandem duplications (ITDs) in the juxtamembrane domain or mutations in the activating loop of FLT3. The consequence of either FLT3-ITD or activating loop mutations is the constitutive activation of the tyrosine kinase activity.
Source: Sf9 insect cells using baculovirus.
