Proximity and orientation underlie signaling by the non-receptor tyrosine kinase ZAP70.

Signaling by the antigen receptor of T lymphocytes initiates different developmental transitions, each of which require the tyrosine kinase ZAP70. Previous studies with agonist and antagonist peptides have indicated that ZAP70 might respond differently to different structures of the TCR-CD3 complex induced by bound peptides. The roles of membrane proximity and orientation in activation of ZAP70...

CCM2 Mediates Death Signaling by the TrkA Receptor Tyrosine Kinase

The TrkA receptor tyrosine kinase is crucial for differentiation and survival of nerve-growth-factor-dependent neurons. Paradoxically, TrkA also induces cell death in pediatric tumor cells of neural origin, via an unknown mechanism. Here, we show that CCM2, a gene product associated with cerebral cavernous malformations, interacts with the juxtamembrane region of TrkA via its phosphotyrosine bi...

Regulation of Macrophage Polarization by RON Receptor Tyrosine Kinase Signaling

The M1 and M2 states of macrophage polarization are the two extremes of a physiologic/phenotypic continuum that is dynamically influenced by environmental signals. The M1/M2 paradigm is an excellent framework to understand and appreciate some of the diverse functions that macrophages perform. Molecular analysis of mouse and human macrophages indicated that they gain M1 and M2-related functions ...

Receptor tyrosine kinase signaling in vascular development.

The formation and maintenance of the vascular circulatory system is of utmost importance during embryonic and postnatal life. The first organ system to develop is the cardiovascular network of endothelial cells that carry blood cells and metabolites throughout the embryo (1 , 2). Indeed, a functional vascular system is crucial for the rapid growth of postimplantation embryos. The vascular syste...

T cell activation-induced CrkII binding to the Zap70 protein tyrosine kinase is mediated by Lck-dependent phosphorylation of Zap70 tyrosine 315.

The Zap70 protein tyrosine kinase controls TCR-linked signal transduction pathways and is critical for T cell development and responsiveness. Following engagement of TCR, the Zap70 undergoes phosphorylation on multiple tyrosine residues that are implicated in the regulation of its catalytic activity and interaction with signaling effector molecules downstream of the TCR. We have shown previousl...
