Protein tyrosine kinases (PTKs) transfer the γ-phosphate group of ATP to tyrosine residues on protein substrates and participate in the regulation of cell proliferation, differentiation, migration, metabolism, and survival. PTKs mainly include receptor tyrosine kinases (RTKs) and nonreceptor ...
The VEGF (vascular endothelial growth factor) signaling pathway is one of the central molecular networks in angiogenesis research. Its role is not limited to promoting endothelial cell proliferation.
