Internalization of the neurotrophin-Trk receptor complex is critical for many aspects of neurotrophin functions. The mechanisms governing the internalization process are unknown. Here, we report that neuronal activity facilitates the internalization of the receptor for brain-derived neurotrophic factor, TrkB, by potentiating its tyrosine kinase activity. Using three independent approaches, we s...

Background: We performed a retrospective analysis to determine the incidence of neurotrophic tropomyosin-receptor kinase (NTRK) fusion in non-small cell lung cancer (NSCLC).

Posttranslational knockdown of a specific protein is an attractive approach for examining its function within a system. Here we introduce phospho-dependent proteolysis targeting chimeras (phosphoPROTACs), a method to couple the conditional degradation of targeted proteins to the activation state of particular kinase-signaling pathways. We generated two phosphoPROTACs that couple the tyrosine ph...

OBJECTIVE The aim of this study was to evaluate the expression of protein tyrosine kinase 2 and protein tyrosine phosphatase non-receptor type 11, which respectively encode focal adhesion kinase protein and src homology 2 domain-containing protein-tyrosine phosphatase 2, in hematopoietic cells from patients with myelodysplastic syndromes. METHODS Protein tyrosine kinase 2 and tyrosine phospha...

The proto-oncogene RET encodes a transmembrane growth neurotrophic receptor with tyrosine kinase (TK) activity. RET mutations are associated with several human neoplastic and nonneoplastic diseases, including thyroid papillary carcinoma, multiple endocrine neoplasia type 2 syndromes, and Hirschsprung's disease. Activation of receptor TKs results in the binding and activation of downstream signa...

The RET tyrosine kinase is a functional receptor for neurotrophic ligands of the glial cell line-derived neurotrophic factor (GDNF) family. Loss of function of RET is associated with congenital megacolon or Hirschsprung's disease, whereas germ-line point mutations causing RET activation are responsible for multiple endocrine neoplasia type 2 (MEN2A, MEN2B, and familial medullary thyroid carcino...

x-linked agammaglobulinemia (xla) is an immunodeficiency caused by mutations in the bruton tyrosine kinase (btk) gene. in order to identify the mutations in btk gene in iranian patients with antibody deficiency, 13 male patients with an xla phenotype from 11 unrelated families were enrolled as the subjects of investigation for btk mutation analysis using pcr-sscp followed by sequencing. five di...

Introduction: Neurotrophins belong to growth factor family and their function is based on their receptors. They bind two types of receptors: p75 and tyrosine kinase. The motoneuron survival or death depends upon the neurotrophic factors. Recent studies have demonstrated that axotomy in peripheral nerve induces apoptosis of motoneuron. Deprenyl or Selegiline is known as a drug with neuroprote...

Brain-derived neurotrophic factor (BDNF)/tyrosine receptor kinase (TRK) signaling pathway activates a wide range of downstream intracellular cascades, regulating neuronal development and plasticity, long-term potentiation, and apoptosis. The NTRK family encodes the receptors TRKA, TRKB, and TRKC, to which the neurotrophins, nerve growth factor (NGF), BDNF and neurotrophin-3 (NT-3) bind, respect...
