Gene Information

human ... FLT3(2322)

General description

FLT3 (fms-related tyrosine kinase 3) is a tyrosine kinase receptor and the gene is localized to human chromosome 13q12. The encoded protein is composed of 993 amino acids, and consists of five immunoglobulin (Ig)-like domains in its exoplasmic region. It is also composed of a transmembrane region, a juxtamembrane domain, and two tyrosine kinase domains in its intracellular domain. The tyrosine kinase domains are linked via a kinase-insert domain.

Biochem/physiol Actions

FLT3 (fms-related tyrosine kinase 3), upon interaction with its ligand, undergoes conformational changes to form homodimers. This results in phosphorylation and activation of downstream signaling pathways including phosphatidylinositol 3-kinase (PI3K/AKT), mitogen-activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK) and signal transducer and activator of transcription 5 (STAT5) pathways. Internal tandem duplication (ITD) mutation or a point mutation in juxtamembrane domain-coding region or within the activation loop domain, respectively, of this gene lead to its constitutive action. FLT3/ITD mutation is associated with later stages of acute myeloid leukemia (AML) pathogenesis. These patients have poor prognosis.

Supplied in 50 mM Tris-HCl, pH 7.5, with 150 mM NaCl, 0.25 mM DTT, 0.1 mM EGTA, 0.1 mM EDTA, 0.1 mM PMSF, and 25% glycerol.

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. FLT3 mutations

Fms-like tyrosine kinase 3 internal tandem duplication (FLT3-ITD) is frequently detected in acute myeloid leukemia (AML) patients and is associated with a dismal long-term prognosis. FLT3 tyrosine kinase inhibitors provide short-term disease control, but relapse invariably occurs within months. Pim

Patients with high FLT3 internal tandem duplication allelic ratios (FLT3/ITD-ARs) have a poor prognosis. Single-nucleotide polymorphism/comparative genomic hybridization, single-cell PCR and colony-forming assays were used to evaluate genotypic evolution of high FLT3/ITD-ARs in 85 acute myeloid leukemia (AML) patients. Microarrays

FLT3-internal tandem duplication (ITD) mutations are found in approximately 30% of patients with acute myeloid leukemia (AML). FLT3 inhibitors have shown clinical activity in AML with FLT3-ITD, but responses are usually short-lived. This study examined 69 FLT3-mutated patients with AML
