FMS-like tyrosine kinase 3 (Flt‑3), also named Fetal liver kinase-2 (Flk-2) is a member of the class III receptor tyrosine kinase subfamily and plays a role in normal hematopoiesis. The classs III RTK family, which includes Flt-3, KIT, SCFR and CSF1R share a conserved architecture of an extracellular domain (ECD) with five immunoglobulin-like domains, a transmembrane domain and an intracellular region with a juxtamembrane domain and two intracellular tyrosine-kinase domains. The ECD of human Flt-3 shares 85% amino acid sequence identity with mouse Flt-3. Flt-3 expression has been detected in various tissues, including placenta, gonads, and tissues of nervous and hematopoietic origin (1). Among hematopoietic cells, the expression of Flt-3 was found to be restricted to the highly enriched stem/progenitor cell populations (2). The ligand for Flt-3 has been identified as Flt-3 ligand (Flt-3L or FL) and activation of Flt-3 signaling mediates cell survival, cell proliferation, and differentiation of hematopoietic progenitor cells (1). Flt-3 has been implicated in several diseases, including autoimmune diseases, such as rheumatoid arthritis, as well as in acute myeloid leukemia where around one-third of patients carry a Flt-3 mutation which drives the disease and is correlated with poor prognosis (3-5). Our Avi-tag Biotinylated Flt‑3 features biotinylation at a single site contained within the Avi-tag, a unique 15 amino acid peptide. Protein orientation will be uniform when bound to streptavidin-coated surface due to the precise control of biotinylation and the rest of the protein is unchanged so there is no interference in the protein's bioactivity.
