Autor: Polina Kornilov, Sharon Ebner-Bennatan, Zohar Tiran, Eti Patrich, Ari Elson, Asher Peretz, Bernard Attali

Publikováno v: Journal of Biological Chemistry. 287:27614-27628

Non-receptor-tyrosine kinases (protein-tyrosine kinases) and non-receptor tyrosine phosphatases (PTPs) have been implicated in the regulation of ion channels, neuronal excitability, and synaptic plasticity. We previously showed that protein-tyrosine

BACKGROUND AND PURPOSE Pathological angiogenesis is associated with various human diseases, such as cancer, autoimmune diseases and retinopathy. The angiopoietin (Ang)–Tie2 system plays critical roles in several steps of angiogenic remodelling. Her

A Novel Recombinant Soluble Splice Variant of Met Is a Potent Antagonist of the Hepatocyte Growth Factor/Scatter Factor-Met Pathway

Publikováno v: Clinical Cancer Research. 14:4612-4621

Purpose: The Met receptor tyrosine kinase and its ligand, hepatocyte growth factor/scatter factor (HGF/SF), are involved in a wide range of biological activities, including cell proliferation, motility, invasion, and angiogenesis. The HGF/SF-Met sign

Publikováno v: Molecular and Cellular Biology. 23:5460-5471

cyt-PTP epsilon is a naturally occurring nonreceptor form of the receptor-type protein tyrosine phosphatase (PTP) epsilon. As such, cyt-PTP epsilon enables analysis of phosphatase regulation in the absence of extracellular domains, which participate

Phosphorylation-dependent Regulation of Kv2.1 Channel Activity at Tyrosine 124 by Src and by Protein-tyrosine Phosphatase ε

Autor: Ari Elson, Asher Peretz, Zohar Tiran, Bernard Attali

Publikováno v: Journal of Biological Chemistry. 278:17509-17514

Voltage-gated potassium (Kv) channels are a complex and heterogeneous family of proteins that play major roles in brain and cardiac excitability. Although Kv channels are activated by changes in cell membrane potential, tyrosine phosphorylation of ch
