Feline McDonough Sarcoma-like tyrosine kinase (FLT3) (also known as FLK2 (fetal liver tyrosine kinase 2), STK-1 (stem cell tyrosine kinase 1) or CD135) is a member of the class III receptor tyrosine kinase family involved in the differentiation, proliferation and survival of hematopoietic progenitor cells and of dendritic cells. Upon FLT3 ligand (FL) binding, the receptor forms dimers and is phosphorylated. Consequently, adapter and signaling molecules bind with the active receptor and trigger the activation of various pathways downstream including PI3K/Akt and MAPK cascades (Grafone T et al. 2012).

The RAS-RAF-MEK-ERK pathway regulates processes such as proliferation, differentiation, survival, senescence and cell motility in response to growth factors, hormones and cytokines, among others. Binding of these stimuli to receptors in the plasma membrane promotes the GEF-mediated activation of RAS at the plasma membrane and initiates the three-tiered kinase cascade of the conventional MAPK cascades. GTP-bound RAS recruits RAF (the MAPK kinase kinase), and promotes its dimerization and activation (reviewed in Cseh et al, 2014; Roskoski, 2010; McKay and Morrison, 2007; Wellbrock et al, 2004). Activated RAF phosphorylates the MAPK kinase proteins MEK1 and MEK2 (also known as MAP2K1 and MAP2K2), which in turn phophorylate the proline-directed kinases ERK1 and 2 (also known as MAPK3 and MAPK1) (reviewed in Roskoski, 2012a, b; Kryiakis and Avruch, 2012). Activated ERK proteins may undergo dimerization and have identified targets in both the nucleus and the cytosol; consistent with this, a proportion of activated ERK protein relocalizes to the nucleus in response to stimuli (reviewed in Roskoski 2012b; Turjanski et al, 2007; Plotnikov et al, 2010; Cargnello et al, 2011). Although initially seen as a linear cascade originating at the plasma membrane and culminating in the nucleus, the RAS/RAF MAPK cascade is now also known to be activated from various intracellular location. Temporal and spatial specificity of the cascade is achieved in part through the interaction of pathway components with numerous scaffolding proteins (reviewed in McKay and Morrison, 2007; Brown and Sacks, 2009). The importance of the RAS/RAF MAPK cascade is highlighted by the fact that components of this pathway are mutated with high frequency in a large number of human cancers. Activating mutations in RAS are found in approximately one third of human cancers, while ~8% of tumors express an activated form of BRAF (Roberts and Der, 2007; Davies et al, 2002; Cantwell-Dorris et al, 2011).
Signal transducer and activator of transcription (STAT) constitutes a family of universal transcription factors. STAT5 refers to two highly related proteins, STAT5A and STAT5B, with critical function in cell survival and proliferation. Several upstream signals including cytokines and growth factors can trigger STAT5 activation.
FLT3 is a member of the Class III Receptor Tyrosine Kinase Family, which also includes FMS, KIT, PDGFRA and PDGFRB. It binds the cytokine FLT3LG (Hannum et al. 1994), which regulates differentiation, proliferation and survival of hematopoietic progenitor cells and dendritic cells.
FLT3LG is probably dimeric. Binding to monomeric FLT3 induces receptor dimerization (Verstraete et al. 2011, Grafone et al. 2012), which promotes phosphorylation of the tyrosine kinase domain, activating the receptor and consequently the downstream effectors. Early studies of FLT3 using a chimeric receptor composed of the extracellular domain of human FMS and the transmembrane and cytoplasmic domains of FLT3 demonstrated the activation of PLCG1, RASA1, SHC, GRB2, VAV, FYN, and SRC pathways. PLCG1, SHC, GRB2, and FYN were found to directly associate with the cytoplasmic domain of FLT3 (Dosil et al. 1993). Later studes using the full-length human receptor identified that FLT3LG binding to FLT3 leads to FLT3 autophosphorylation, association of FLT3 with GRB2, tyrosine phosphorylation of SHC and CBL, formation of a complex that includes CBL, the p85 subunit of PI3K and GAB2, and tyrosine phosphorylation of GAB1 and GAB2 and their association with PTPN11 (SHP-2) and GRB2. PTPN11 (SHP-2), but not PTPN6 (SHP-1) binds GRB2 directly and becomes tyrosine-phosphorylated in response to FLT3LG stimulation. INPP5D (SHIP) also becomes tyrosine-phosphorylated after FLT3LG stimulation but binds to SHC. GAB1 and GAB2 are rapidly tyrosine phosphorylated after FLT3LG stimulation of cells, interacting with tyrosine-phosphorylated PTPN11, p85 subunit of PI3K, GRB2, and SHC (Zhang & Broxmeyer 2000). GAB may mediate the downstream activation of PTPN11, PI3K and thereby PDK1 and AKt which activate the mTOR pathway (Grafone et al. 2012), and possibly the Ras/Raf/MAPK pathway. (Zhang et al. 1999, Marchetto et al. 1999, Zhang e& Broxmeyer 2000). Activation of FLT3 leads to limited activation of STAT5A via a JAK-independent mechanism (Zhang et al. 2000).
FLT3 is mutated in about 1/3 of acute myeloid leukemia (AML) patients, either by internal tandem duplications (ITD) of the juxtamembrane domain or by point mutations usually involving the kinase domain (KD). Both types of mutation constitutively activate FLT3 (Small 2006).
Feline McDonough Sarcoma-like tyrosine kinase (FLT3) is a member of the class III tyrosine kinase receptor family. Ligand binding induces conformational changes in the FLT3 receptor, which facilitates its dimerization and autophosphorylation. Once fully active, FLT3 receptors can associate with growth factor receptor-bound protein 2 (GRB2) and facilitate downstream regulation of effectors (Masson et al. 2009, Chonabayashi et al. 2013). Experiments confirming this event were performed in mouse cells.
Feline McDonough Sarcoma-like tyrosine kinase (FLT3) is a member of the class III tyrosine kinase receptor family. Ligand binding induces conformational changes in FLT3 receptor, which facilitates its dimerization. This process exposes phosphate acceptor sites in the catalytic domain of FLT3. Subsequently, FLT3 autophosphorylates at these sites. Several phosphorylation sites have been reported and there may be more modifications required to fully activate FLT3 (Heiss et al. 2006, Masson et al. 2009, Razumovskaya et al. 2009). Experiments confirming this event were performed in mouse cells.

Ligand binding induces conformational changes in the FLT3 receptor, which facilitates its dimerization and autophosphorylation. Once fully active, tyrosine-protein phosphatase non-receptor type 11 (PTPN11) has been reported to directly bind to the Y599 site of Flt3 receptors thereby facilitating downstream regulation of effectors (Heiss et al. 2006, Nabinger et al. 2013). Experiments confirming this event were performed in mouse cells. Interaction of FLT3 with PTPN11 is known to trigger STAT5 activation in various pathological conditions (Mizuki M et al. 2000, Rocnik JL et al. 2006).

Feline McDonough Sarcoma-like tyrosine kinase (FLT3) is a member of the class III tyrosine kinase receptor family. Ligand binding induces conformational changes in the FLT3 receptor, which facilitates its dimerization and autophosphorylation. Once fully active, FLT3 receptors can associate with growth factor receptor-bound protein 2 (GRB2), which then recruits Son of sevenless homolog 1 (SOS1). Consequently, this triggers the activation of the ERK signaling cascade (Li et al. 1993).
Son of sevenless homolog 1 (SOS1) is the guanine nucleotide exchange factor (GEF) for rat sarcoma (RAS) protein. SOS1 activates RAS nucleotide exchange from the inactive form (bound to GDP) to an active form (bound to GTP).
Feline McDonough Sarcoma-like tyrosine kinase (FLT3) is a member of the class III tyrosine kinase receptor family. Ligand binding induces conformational changes in the FLT3 receptor, which facilitates its dimerization and autophosphorylation. Tyrosine-protein kinase HCK (HCK) associates with the phosphorylated Y589 and Y591 residues of FLT3. This binding results in further phosphorylation of the FLT3 receptor to make it fully active (Heiss et al. 2006, Mitina et al. 2007). There may be more unknown binding sites for HCK on FLT3.

The importance of the RAS/RAF MAPK cascade is highlighted by the fact that components of this pathway are mutated with high frequency in a large number of human cancers. Activating mutations in RAS are found in approximately one third of human cancers, while ~8% of tumors express an activated form of BRAF (Roberts and Der, 2007; Davies et al, 2002; Cantwell-Dorris et al, 2011).
