Protein tyrosine phosphatase non-receptor type 2 as the therapeutic target of atherosclerotic diseases: past, present and future

Frontiers in Pharmacology, 2023
Tyrosine-protein phosphatase non-receptor type 2(PTPN2), an important member of the protein tyrosine phosphatase family, can regulate various signaling pathways and biological processes by dephosphorylating receptor protein tyrosine kinases. Accumulating

Neuroblastoma tyrosine kinase signaling networks involve FYN and LYN in endosomes and lipid rafts. [PDF]

PLoS Computational Biology, 2015
Protein phosphorylation plays a central role in creating a highly dynamic network of interacting proteins that reads and responds to signals from growth factors in the cellular microenvironment.

Tyrosine 402 phosphorylation of Pyk2 is involved in ionomycin-induced neurotransmitter release. [PDF]

PLoS ONE, 2014
Protein tyrosine kinases, which are highly expressed in the central nervous system, are implicated in many neural processes. However, the relationship between protein tyrosine kinases and neurotransmitter release remains unknown.

Receptor Protein Tyrosine Kinases and Phosphatases

Cold Spring Harbor Symposia on Quantitative Biology, 1992
It is clear that the number of receptor PTKs and PTPs encoded by a typical vertebrate genome is rather large. Although the signal pathways activated by the receptor PTKs may in many cases be common, specificity is provided by the ligand-binding domain and the availability of ligand.

Association of the erythropoietin receptor with protein tyrosine kinase activity. [PDF]

Proceedings of the National Academy of Sciences, 1992
We have examined the signal transduction mechanism of the hematopoietic growth factor erythropoietin (Epo). Epo stimulation of Ba/F3 cells transfected with the Epo receptor resulted in increases in tyrosine phosphorylation of proteins of 97, 75, and 55 kDa.

Grb2 binding induces phosphorylation-independent activation of Shp2

Communications Biology, 2021
Lin et al. investigate the interactions between adaptor protein, Grb2, and the ubiquitously expressed protein tyrosine phosphatase, Shp2. They find that monomeric Grb2 can activate Shp2 and its downstream signalling in the absence of up-regulation of ...

Tyrosine phosphorylation of the BRI1 receptor kinase occurs via a posttranslational modification and is activated by the juxtamembrane domain

Frontiers in Plant Science, 2012
In metazoans, receptor kinases control many essential processes related to growth and development and response to the environment. The receptor kinases in plants and animals are structurally similar but evolutionarily distinct and thus while most animal ...

Helicobacter Pylori Targets the EPHA2 Receptor Tyrosine Kinase in Gastric Cells Modulating Key Cellular Functions

Cells, 2020
Helicobacter pylori, a stomach-colonizing Gram-negative bacterium, is the main etiological factor of various gastroduodenal diseases, including gastric adenocarcinoma. By establishing a life-long infection of the gastric mucosa, H.

Crystal structure of the kinase domain of a receptor tyrosine kinase from a choanoflagellate, Monosiga brevicollis.

PLoS ONE, 2023
Genomic analysis of the unicellular choanoflagellate, Monosiga brevicollis (MB), revealed the remarkable presence of cell signaling and adhesion protein domains that are characteristically associated with metazoans. Strikingly, receptor tyrosine kinases,

Structural insights into characterizing binding sites in EGFR kinase mutants [PDF]

Journal of Chemical Information and Modeling, 2018, 2018
Over the last two decades epidermal growth factor receptor (EGFR) kinase has become an important target to treat non-small cell lung cancer (NSCLC). Currently, three generations of EGFR kinase-targeted small molecule drugs have been FDA approved. They nominally produce a response at the start of treatment and lead to a substantial survival benefit for ...
