Src homology 2 (SH2) domain containing protein tyrosine phosphatase-1 (SHP-1) dephosphorylates VEGF Receptor-2 and attenuates endothelial DNA synthesis, but not migration*Journal of Molecular Signaling - Tập 3 - Trang 1-13 - 2008

Vascular endothelial growth factor receptor-2 (VEGFR-2, KDR), a receptor tyrosine kinase, regulates mitogenic, chemotactic, hyperpermeability, and survival signals in vascular endothelial cells in response to its ligand vascular permeability factor/ vascular endothelial growth factor (VPF/VEGF). SHP-1 is a protein tyrosine phosphatase known to negatively regulate signaling from receptors such as E...... hiện toàn bộ
Multiple paxillin binding sites regulate FAK functionJournal of Molecular Signaling - Tập 3 - Trang 1-11 - 2008

FAK localization to focal adhesions is essential for its activation and function. Localization of FAK is mediated through the C-terminal focal adhesion targeting (FAT) domain. Recent structural analyses have revealed two paxillin-binding sites in the FAT domain of FAK. To define the role of paxillin binding to each site on FAK, point mutations have been engineered to specifically disrupt paxillin ...... hiện toàn bộ
AKAP12 and AKAP5 form higher-order hetero-oligomersJournal of Molecular Signaling - Tập 6 - Trang 1-12 - 2011
Shujuan Gao, Hsien-yu Wang, Craig C Malbon
The family of A-kinase-anchoring proteins, AKAPs, constitutes a group of molecular scaffolds that act to catalyze dynamic interactions of protein kinase A, protein kinase C, tyrosine kinases, G-protein-coupled receptors and ion channels. AKAP5 (MW ~47 kDa) and AKAP12 (MW ~191 kDa) homo-oligomerize, but whether or not such AKAPs can hetero-oligomerize into supermolecular scaffolds of increased comp...... hiện toàn bộ
Estradiol effects on the dopamine transporter – protein levels, subcellular location, and functionJournal of Molecular Signaling - Tập 1 - Trang 1-14 - 2006

The effects of estrogens on dopamine (DA) transport may have important implications for the increased incidence of neurological disorders in women during life stages when hormonal fluctuations are prevalent, e.g. during menarche, reproductive cycling, pregnancy, and peri-menopause. The activity of the DA transporter (DAT) was measured by the specific uptake of 3H-DA. We found that low concentratio...... hiện toàn bộ
EGF regulates tyrosine phosphorylation and membrane-translocation of the scaffold protein Tks5Journal of Molecular Signaling - Tập 8 - Trang 1-8 - 2013

Tks5/FISH is a scaffold protein comprising of five SH3 domains and one PX domain. Tks5 is a substrate of the tyrosine kinase Src and is required for the organization of podosomes/invadopodia implicated in invasion of tumor cells. Recent data have suggested that a close homologue of Tks5, Tks4, is implicated in the EGF signaling. Here, we report that Tks5 is a component of the EGF signaling pathway...... hiện toàn bộ
